To explore the variation among cultivars and species, the pollen morphological traits like pollen area, perimeter, radius, length, width and height and filament length were subjected to descriptive statistics and cluster analysis. Among the four cultivated species, G. barbadense recorded higher values for all the pollen parameters; however, higher values for filament length were noted in G. hirsutum. Cluster analysis formed three clusters which were Cluster I for G. barbadense, cluster II for G. hirsutum and cluster III was occupied by diploids (G. arboreum and G. herbaceum).

    查看更多>>摘要：The use of natural fibers is recorded from pre historic era and recorded between 3000 to 2000 BC, and the weaving of cotton was well established in unified India. Improvements in machines for spinning, weaving, etc., beginning in the 1700s and revolutionized Eli Whitney’s invention of the cotton gin in 1793 helped cotton become king of the fibers (Fisher, 1981). Natural fibers have been used for centuries to protect human against warm and cold weather. Until the last 100 years or so, the only fibersused by mankind were natural fibers. Hemp, the oldest cultivated fiber plant, originated in Southeast Asia, then spread to China, where reports of cultivation date to 5000-6000 years ago. The art of handmade weaving and spinning linen was already well developed in Egypt by 3400 BC, indicating that flax was cultivated sometime before that date. Reports of the spinning of cotton in India date back to 3000 BC. The manufacture of silk and silk products originated in the highly developed Chinese culture during 2640 BC. New fiber plants were also discovered and their use explored. In the 18th and 19th centuries, the Industrial Revolution encouraged the further invention of machines for use in processing various natural fibers, resulting in a tremendous upsurge in natural fiber production.

    查看更多>>摘要：Phule JLA 0603, diploid cotton variety, was derived by hybridization through pedigree selection method from across JLA-1693 x AKA-9110. It has good fibre properties medium staple length (24.6 mm), and good (23.8 g/t) staple strength. The variety wasresistant to bacterial leaf Dlight (BLB) and moderately susceptible to Altemaria leaf blight (ALB) and grey mildew disease. Phule JLA-0603 gave highest seed cotton yield (1515 kg/ha) over zonal check DLSa-17 (1367 kg/ha) and local check (1351 kg/ha), which is 10.78 and 12.14 per cent higher over DLSa-17 and local check, respectively in coordinated varietal trials. Thus it was released and named Phule JLA-0603 for commercial cultivation in south zone of India comprising states of Andhra Pradesh, Telangana, Tamil Nadu and Karnataka under rainfed conditions.

The analysis of variance involving a set of thirty two Gossypium hirsutum genotypes for sixteen characters viz., days to first flowering,days to 50 per cent flowering, plant height, monopodia sympodia and bolls/plant, boll weight, seed index, lint index, ginning percentage, upper half mean length, bundle strength, fibre fineness, uniformity index, fibre elongation percentage and seed cotton yield (kg/ha) revealed highly significant mean sum of squares for all the characters except sympodia/plant indicating greater diversity among the genotypes. The value of Phenotypic Coefficient of Variation (PCV) is greater than Genotypic Coefficient of Variation (GCV) indicated that the apparent variation is not only due to genotypes but due to influence of environment also. The difference between the estimates of PCV and GCV were low for all the charactersexcept monopodia and sympodia/plant thereby indicating that lesser role played by the environment in the expression of these traits. The characters like days to first flowering, bolls/plant, boll weight, seed index, ginning percentage, upper half mean length, bundle strength, fibre fineness, uniformity index, fibre elongation percentage and seed cotton yield (kg/ha) exhibited high broad sense of heritability and moderate sense of heritability was observed for days to 50 pre cent flowering, plant height, and monopodia/plant. High heritability coupled with high genetic advance as a per cent of mean was recorded for bolls/plant and seed cotton yield indicated the major role of additive gene action in the inheritance of these characters. Hence, these characters may serve as an effective selection parameter during breeding programme in the upland cotton improvement programme.

    查看更多>>摘要：The experiment was commenced to determine the distinctness, uniformity and stability characteristics of fifty germplasm accessions of Egyptian cotton. The experiment was carried out using augmented Block Design during summer 2021 at the Department ofCotton, TNAU. Five principal components were defined through Principal Component Analysis (PCA), accounting for 97.62 pre cent of the total variation. First principal component (PC 1) was associated with stem pigmentation (0.967) and petal spot (0.236).Second principal component (PC 2) was associated with petal spot (0.934) and boll tip (0.238). The traits leaf hairiness, leaf nectaries, stigma position, boll colour and boll surface had the highest diversity index (3.912). Stem pigmentation (3.391) hadthe lowest diversity index, followed by stem hairiness (3.760) and petal spot (3.846). Based on UPGMA method, the genotypes were divided into five distinct clusters. Cluster III had the most genotypes (29), while Cluster I and II had only one genotype.Genotypes namely GP(B) 185 - NDGB 84, GP(B) 184 - NDGB 80 and GP(B) 46 EC - 136452/A occupied the convex of the hull and had the highest point among the variables.

    查看更多>>摘要：CRISPR-Cas9 is a valuable gene editing tool in plant science research. The presence of clustered repeats was first discovered by Ishino et al., (1987) when the loci containing repeat sequences with an unknown function found in the Escherichia coZi genome. Prokaryotes have CRISPR family throughout the genome was discovered by Mojka et at, (2000) and the name CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) was coined and designed as Cas genes by Jansen et al., (2002). First experimental evidence was reported for CRISPR adaptive immunity and the CRISPR complexes cleave the RNA and the tracr RNA forms a duplex structure with CrRNA in association with Cas 9 by Barrangou et al., (2007). The PAM (Protospacer Adjacent Motif) is a motif with sequence NGG (any, guanine, guanine) is specific to Streptococcus pyogenes and 52 -NAG (any, adenine, guanine) the origin of spacers and adaptive immune system was reported by Bolotin et al., (2005) and Pourcel et al., (2005). The CRISPR acts upon DNA targets and the spacers are converted in to mature crRNAs that act on small guide RNAs (Marrafini et al., 2008, Brouns et al., 2008). The Cas 9 is guided by spacer sequences and cleaves target DNA via Double Stranded Breaks (Garneu et al., 2010).

    查看更多>>摘要：Thirty two genetic male sterility based intra arboreum cotton hybrids were evaluated against the hybrid check AAH-1 during kharif2020 at Cotton Research Area, CCS Haryana Agricultural University, Hisar for yield and its attributes. The analysis of variance revealed that the hybrids differed significantly for all the characters under study indicating presence of considerable genetic variability between the genotypes. These hybrids exhibited heterosis over standard check for all the traits studied. Correlation analysis showed significantly higher and positive correlation between seed cotton yield and lint yield describing corresponding increase in lint yield with the increase in seed cotton yield. Eight hybrids viz., GMS 1 x HD 535, RGMS 5 x GCD 91, GMS 1 x HD 548, GMS 1 x GCD 308 (AAH38), RGMS 5 x HD 535, GMS 1 x DMP 44 (AAH 44), GMS 1 x NP 15 (HD 123 x HD 462) (AAH 43) and RGMS 5 x HD 544 were found promising based on significantly higher seed cotton yield and standard heterosis. Therefore, these promising cross combinations can be exploited for their hybrid vigour.

    查看更多>>摘要：The study was undertaken to find out the association between seed cotton yield, its component traits and fibre quality characters in upland cotton (Gossypium hirsutum L.). Fifty genotypes of upland cotton were sown in a randomized block design with three replications at the Research Area of Cotton Section, Department of Genetics and Plant Breeding, CCS Haryana Agricultural University, Hisar during kharif, 2020. Seed cotton yield exhibited a highly significant positive correlation at genotypic level with number of monopods (0.674), number of bolls (0.937), boll weight (0.533), seed index (0.725), ginning outturn (0.422 and 0.326), fibre length (0.587), fibre uniformity (0.560) and fibre strength (0.380). It showed non significant correlation with days to 50 per cent flowering and fibre fineness. There was a strong association of fibre length with fibre uniformity ( 1.007) and fibre strength (0.686) at both genotypic and phenotypic level. However, it had non significant correlation with fibre fineness at both the levels.

    查看更多>>摘要：Sixty Front Line Demonstrations (FLDs) on cotton intercropping with pulses were carried out in a total 60 hectares of 61 farmers’ fields in 23 villages in Madurai, Virudhunagar and Thoothukudi Districts of Southern Tamil Nadu during winter irrigatedor rainfed seasons (August 2018 to January 2017-2018, 2018-2019 and 2019-2020. The FLD on cotton intercropping with black gram and green gram were compared with farmers’ practice. In FLD, latest cotton varieties (SVPR 4, SVPR 5 and CO 17), black gram (VBN 6, VBN 8 and MDU 1) and green gram (CO 8) intercropping, balanced fertilizer application and integrated pest management practices were adopted. In farmers’ practice, use of mixed varieties, broadcasting, without intercropping, unbalanced fertilizer application and irregular use of insecticides were followed. The results revealed that adoption of improved varieties and integrated management practices recorded higher mean kapas yield of 2160 and 1583 kg/ha under irrigated and rainfed conditions, respectively as compared to famers method of cultivation (1836 and 1403 kg/ha). Thus the yield advantage of 17.58 and 13.02 per cent under irrigated and rainfed conditions, respectively than control was observed. Among the varieties, CO 17 performed better than other varieties during all the years of study. The Land Equivalent Ratio was more than one indicating the higher efficiency of yield production of cotton with intercropping of pulses than sole cotton. Higher mean net profit of Rs 52, 760/ha and Rs 36,298/ha under irrigated and rainfed conditions respectively were associated with the use of high yielding varieties and improved production technologies (Rs 29,165 and 20,674/ha) and higher benefit cost ratio than farmers’ practice. Thus cultivation ofnew varieties with improved production technologies gained an additional economic benefit of Rs. 28,642 and 16,895/ha as compared to existing varieties with farmers’ method. It can be concluded from the Front Line Demonstrations that adoption of modernvarieties of cotton with intercropping lead higher yield, better land use efficiency and higher economic benefits which will pave way for sustainable cotton production .
