Effects of Different Endosperm Phenotypes on Agronomic Traits and Yield in Sorghum
In order to explore the potential effects of endosperm texture and starch type on grain yield,plant height,and other agronomic traits in sorghum,this study conducted artificial hybridization between a waxy sorghum line as the male parent and a floury sorghum line as the female parent in 2021.In 2022,a sample survey was conducted on the F2 population of recombinant endosperm phenotype to identify sample endosperm phenotypes,measure grain yield,plant height,and other agronomic traits for analysis.The results showed that plants with the waxy starch had significantly reduced panicle weight,while those with floury endosperm texture had significantly reduced panicle weight,1000-grain weight and plant height.Nonetheless,high-yielding lines with a waxy starch type or floury endosperm texture can be chosen,and breeding efforts for these lines must be prioritized in order to effectively discover high-yielding lines with this phenotype.
