Genetic studies on yield traits of late sown elite kabuli chickpea lines

Abstract

Present study was carried out to assess the genetic variability and correlation for yield and its contributing traits using 89 elite lines of kabuli during rabi 2018-19. Analysis of variance revealed, the significant differences among the lines for all the traits indicated that the presence of sufficient amount of genetic variability among the lines. High GCV% and PCV % accounted for the traits seed yield per plant followed by stem height at initiation of first flower, number of effective pods per plant, total number of pods per plant and biological yield per plant. High heritability coupled with high genetic advance as percentage of mean noted for seed yield per plant, stem height at initiation of first flower and number of effective pods per plant. Selection of the line had more than 25 cm stem height at initiation of first flower, viz. FLIP12-278C, FLIP12-161C, JGK-2018-5, ICCV181309 and ICCV181305, would be suitable for mechanical harvesting. Seed yield per plant showed highly significant and positive association with biological yield per plant , harvest index, 100 seed weight , total number of effective pods per plant, while highly significant but negative correlation with days to pod initiation followed by days to 50% flowering and days to flower initiation. Lines identified having maximum 100 seed weight, viz. JGK-2018-1, JGK-2018-2, JGK-2018-3,JGK-2018-4, RVSVT-K-105, RVSVT-K-110 and ICCV181307.The diverse promising lines could be used in chickpea breeding programme and improved nutritional foodsecurity.
