    查看更多>>摘要：Background Anthonomus grandis grandis is the main cotton pest in the Americas,with the potential to become a pest in other continents.The insect uses the plant's reproductive organs for feeding,oviposition,and survival strategies in the off-season,sheltering in dry bolls.This study aimed to know the reproductive potential,feeding,longevity,and morphometric characteristics of boll weevils from dry bolls,squares,and traps.Adults were obtained from infested squares,dry bolls,and traps installed in cotton fields and the Caatinga area.Thirty weevil pairs were maintained in the laboratory to assess the oviposition,feeding holes,longevity,and morphometric measurements of the parental and F1 generations.Results In the parental generation,boll weevils from traps(the Caatinga area and cotton cultivation)showed greater reproductive potential.Boll weevils from squares and the Caatinga area showed greater feeding activity compared with those from cotton cultivation.Greater rostrum length,thorax+abdomen length,and abdomen width were observed in boll weevils from cotton cultivation and dry bolls.The origin of boll weevils parental generation did not affect progeny emergence time.The F1 generation of boll weevils showed significant differences in average lon-gevity depending on the origin of different microhabitats.Furthermore,differences in rostrum lengths were observed,with the boll weevils coming from traps installed in cotton cultivation,the Caatinga area,and dry bolls being the largest.Regarding thorax+abdomen length and abdomen width,the highest values were observed in those from the Caatinga area and cotton cultivation.Conclusion It was proven that dry bolls did not affect the reproductive,feeding,and longevity performance of boll weevils,enabling better insect fitness(reproduction and size)in relation to those coming from squares.The use of dry bolls as off-season shelter is an important survival strategy for the boll weevil.

    查看更多>>摘要：Background Globally,the cultivation of cotton is constrained by its tendency for extended periods of growth.Early maturity plays a potential role in rainfed-based multiple cropping system especially in the current era of climate change.In the current study,a set of 20 diverse Gossypium hirsutum genotypes were evaluated in two crop seasons with three planting densities and assessed for 11 morphological traits related to early maturity.The study aimed to identify genotype(s)that mature rapidly and accomplish well under diverse environmental conditions based on the two robust multivariate techniques called multi-trait stability index(MTSI)and multi-trait genotype-ideotype distance index(MGIDI).Results MTSI analysis revealed that out of the 20 genotypes,three genotypes,viz.,NNDC-30,A-2,and S-32 accom-plished well in terms of early maturity traits in two seasons.Furthermore,three genotypes were selected using MGIDI method for each planting densities with a selection intensity of 15％.The strengths and weaknesses of the genotypes selected based on MGIDI method highlighted that the breeders could focus on developing early-maturing genotypes with specific traits such as days to first flower and boll opening.The selected genotypes exhibited positive genetic gains for traits related to earliness and a successful harvest during the first and second pickings.However,there were negative gains for traits related to flowering and boll opening.Conclusion The study identified three genotypes exhibiting early maturity and accomplished well under different planting densities.The multivariate methods(MTSI and MGIDI)serve as novel approaches for selecting desired geno-types in plant breeding programs,especially across various growing environments.These methods offer exclusive benefits and can easily construe and minimize multicollinearity issues.

    Morphological and cytological assessments reveal pollen degradation causes pollen abortion in cotton cytoplasmic male sterility lines

    266-276页
    查看更多>>摘要：Background Understanding the mechanism of male sterility is crucial for producing hybrid seeds and developing sterile germplasm resources.However,only a few cytoplasmic male sterility(CMS)lines of cotton have been produced due to several challenges,like inadequate variation of agronomic traits,incomplete sterility,weak resilience of restorer lines,and difficulty in combining strong dominance.Therefore,the morphological and cytological identification of CMS in cotton will facilitate hybrid breeding.Results Two F2 segregating populations of cotton were constructed from cytoplasmic male sterile lines(HaA and 01 A,maternal)and restorer lines(HaR and 26R,paternal).Genetic analysis of these populations revealed a segre-gation ratio of 3:1 for fertile to sterile plants.Phenotypic analysis indicated no significant differences in traits of flower bud development between sterile and fertile plants.However,sterile plants exhibited smaller floral organs,shortened filament lengths,and anther atrophy on the flowering day in comparison with the fertile plants.When performed scanning electron microscopy(SEM),the two F2 populations revealed morphological variations in the anther epider-mis.Cellular analysis showed no significant differences in pollen development before pollen maturation.Interestingly,between the pollen maturation and flowering stages,the tapetum layer of sterile plants degenerated prematurely,resulting in abnormal pollen grains and gradual pollen degradation.Conclusion The results of this study suggest that fertility-restoring genes are controlled by a single dominant gene.Sterile plants exhibit distinctive floral morphology,which is characterized by stamen atrophy and abnormal anthers.Pollen abortion occurs between pollen maturity and flowering,indicating that premature tapetum degradation may be the primary cause of pollen abortion.Overall,our study provides a theoretical basis for utilizing CMS in hybrid breeding and in-depth investigation of the dominant configuration of cotton hybrid combinations,mechanisms of sterility,and the role of sterile and restorer genes.

    查看更多>>摘要：Background Bt technology has played significant role in controlling bollworms and increasing cotton yield in earlier days of its introduction,a subsequent decline in yield became apparent over time.This decline may be attributed to various environmental factors,pest dynamics,or combination of both.Therefore,the present biophysical survey and questionnaire were designed to evaluate the impact of Bt cotton on bollworms management and its effect on reducing spray costs,targeting farmers with varied landholdings and educational backgrounds.Additionally,data on farmers'cultivated varieties and the prevalence of bollworms and sucking insects in their fields were recorded.Subsequently,about eleven thousand cotton samples from farmer fields were tested for Cry1Ac,Cry2Ab and Vip3A genes by strip test.Results In this analysis,83％of the farmers planting approved varieties believe that Bt technology control boll-worms,while 17％hold contradictory views.Similarly,among farmers cultivating unapproved varieties,77％agree on effectiveness of Bt technology against boll worms,while 23％disagree.On the other hand,67％of farmers planting approved varieties believe that Bt technology does not reduce spray costs,while 33％agree with the effectiveness.Similarly,78％of farmers cultivating unapproved varieties express doubt regarding its role to reduce spray costs,while 22％are in favour of this notion.Differences in opinions on the effectiveness of Bt cotton in controlling boll-worms and reducing spray cost between farmers planting unapproved and approved varieties may stem from several factors.One major cause is the heavy infestation of sucking insects,which is probably due to the narrow genetic vari-ation of the cultivated varieties.Additionally,the widespread cultivation of unapproved varieties(21.67％)is also an important factor to cause different opinions on the effectiveness of Bt cotton.Conclusion Based on our findings,we propose that the ineffective control of pests on cotton crop may be attrib-uted to large scale cultivation of unapproved varieties and non-inclusion of double and triple transgene technologies in country's sowing plan.On the basis of our findings,we suggest cotton breeders,regulatory bodies and legislative bodies to discourage the cultivation of unapproved varieties and impure seed.Moreover,the adoption of double and triple Bt genes in cottons with a broad genetic variation could facilitate the revival of the cotton industry,and pre-senting a promising way forward.

    查看更多>>摘要：Climate deterioration,water shortages,and abiotic stress are the main threats worldwide that seriously affect cot-ton growth,yield,and fiber quality.Therefore,research on improving cotton yield and tolerance to biotic and abiotic stresses is of great importance.The NAC proteins are crucial and plant-specific transcription factors(TFs)that are involved in cotton growth,development,and stress responses.The comprehensive utilization of cotton NACTFs in the improvement of cotton varieties through novel biotechnological methods is feasible.Based on cotton genomic data,genome-wide identification and analyses have revealed potential functions of cotton NAC genes.Here,we com-prehensively summarize the recent progress in understanding cotton NACTFs roles in regulating responses to drought,salt,and Verticillium wilt-related stresses,as well as leaf senescence and the development of fibers,xylem,and glands.The detailed regulatory network of NAC proteins in cotton is also elucidated.Cotton NACTFs directly bind to the pro-moters of genes associated with ABA biosynthesis and secondary cell-wall formation,participate in several biological processes by interacting with related proteins,and regulate the expression of downstream genes.Studies have shown that the overexpression of NACTF genes in cotton and other model plants improve their drought or salt tolerance.This review elucidates the latest findings on the functions and regulation of cotton NAC proteins,broadens our understand-ing of cotton NACTFs,and lays a fundamental foundation for further molecular breeding research in cotton.

    查看更多>>摘要：Lessons learned from past experiences push for an alternate way of crop production.In India,adopting high den-sity planting system(HDPS)to boost cotton yield is becoming a growing trend.HDPS has recently been considered a replacement for the current Indian production system.It is also suitable for mechanical harvesting,which reduc-ing labour costs,increasing input use efficiency,timely harvesting timely,maintaining cotton quality,and offering the potential to increase productivity and profitability.This technology has become widespread in globally cotton growing regions.Water management is critical for the success of high density cotton planting.Due to the problem of freshwater availability,more crops should be produced per drop of water.In the high-density planting system,optimum water application is essential to control excessive vegetative growth and improve the translocation of pho-toassimilates to reproductive organs.Deficit irrigation is a tool to save water without compromising yield.At the same time,it consumes less water than the normal evapotranspiration of crops.This review comprehensively documents the importance of growing cotton under a high-density planting system with deficit irrigation.Based on the current research and combined with cotton production reality,this review discusses the application and future development of deficit irrigation,which may provide theoretical guidance for the sustainable advancement of cotton planting systems.

    查看更多>>摘要：Cotton plays a crucial role in shaping Indian economy and rural livelihoods.The cotton crop is prone to numerous insect pests,necessitating insecticidal application,which increases production costs.The advent of the expression of Bacillus thuringiensis(Bt)insecticidal protein in cotton has significantly reduced the burden of pest without compromising environmental or human health.After the introduction of transgenic cotton,the cultivated area expanded to 22 million hectares,with a 64％increase in adoption by farmers worldwide.Currently,Bt cotton accounts for 93％of the cultivated cotton area in India.However,extensive use of Bt cotton has accelerated resistance development in pests like the pink bollworm.Furthermore,the overreliance on Bt cotton has reduced the use of broad-spectrum pesticides,favouring the emergence of secondary pests with significant challenges.This emphasizes the urgent necessity for developing novel pest management strategies.The high-dose and refuge strategy was initially effective for managing pest resistance in Bt cotton,but its implementation in India faced challenges due to misunderstandings about the use of non-Bt refuge crops.Although gene pyramiding was introduced as a solution,combining mono toxin also led to instances of cross-resistance.Therefore,there is a need for further exploration of biotechnological approaches to manage insect resistance in Bt cotton.Advanced biotechnological strategies,such as sterile insect release,RNA interference(RNAi)-mediated gene silencing,stacking Bt with RNAi,and genome editing using clustered regularly interspaced short palindromic repeats/CRISPR-associated protein(CRISPR-Cas),offer promising tools for identifying and managing resistance genes in insects.Additionally,CRISPR-mediated gene drives and the development of novel biopesticides present potential avenues for effective pest management in cotton cultivation.These innovative approaches could significantly enhance the sustainability and efficacy of pest resistance management in Bt cotton.
