Opis

The present investigation revealed that the magnitude of additive gene action has been found to be higher for plant height, biological yield per plant, harvest index, protein content and tryptophan content therefore early generation selection by using pedigree method will be useful for the improvement of these traits. However, for days to 50% flowering, days to 75% maturity, fertile nodes per plant, pods per plant, seed yield per plant and 100-seed weight, preponderance of dominance variance was observed which imply that selection should be deferred to later generations by using bulk or bulk-pedigree method of breeding. The promising cross combinations like PL-406 x L-649 can be exploited to develop early maturing genotypes and PL-406 x L-651 could be exploited to develop high yielding cultivar in lentil, whereas Vipasa x L-652, PL-406 x L-354 can be exploited for the improvement of quality traits in lentil
