What is Phenotypic Characterization of Wheat Germplasm for Heritability and Dissection of Association Among Post Anthesis Traits Under Variable Sowing Dates about?

Background The world's main crop for producing staple foods is wheat. In South Asia's cotton-wheat cropping system, however, a late cotton harvest causes a delayed wheat planting, which causes significant production losses. Therefore, this study investigated genetic diversity among wheat genotypes for late sowing. Additionally, associations between several yield-related parameters were discovered, along with their direct and indirect implications on the choice of the best genotypes suitable for late planting. Methods Twenty wheat genotypes/advance lines were evaluated under two sowing times, i.e., normal sowing and late sowing for two consecutive years (2019–2021). Data regarding post anthesis traits were collected. Results The findings showed that planting dates and genotypes substantially (p < 0.05) impacted all characteristics. Genotype ‘9622’ proved consistent for grain yield by showing the lowest reduction under late sowing. Similar to this, assessments of heritability, correlation, and path coefficients showed that heredity and association strength varied with various sowing dates. Number of spikelets per spike, spike length and biological yield showed the highest correlation
