Nature and magnitude of genetic variation in the macro x microsperma genepool of lentil

The experimental material comprised the prognies of three crosses, namely, HPL 4 x L 830 (123 progenies), HPL 1 x L 1282 (295) and HPL 3 x L 1282 (170) Involvlng HPL 4, HPL 1 and HPL 3 as macrosperma and L 830 and L 1282 as microsperma types. The progenies were evaluated in Augmented Block Design. Data was recorded with respect to seed yield, harvest index, pod length seeds per pod, single seed weight, days to flowering and days to maturity Mean performance of the progenies showed that 7 progenies in HPL x L 830, 18 progenies in HPL 1 x L 1282 and 14 progenies in HPL 3 x1 1282 cross for seed yield were found to be significantly superior to the best check viz., HPL 5 (Vipasha). Variance analysis revealed a wide range of variability for all the traits except phenological traits where the range of variation was narrow. The magnitude of co-efficient of variation (CV) was high for harvest index, seed yield, seeds per pod and seed weight, whereas it was least for days to maturity and days to flowering. Heritability (bs) was high for the traits and crosses studied. High heritability was found to be coupled with high genetic advance for seed yield, harvest Ifldex, seed weight and seeds per pod.
