Genetic Nature and Selection Index in Lentil PDF

Abul Kalam Azad

The whole work of the present investigation was carried out under two separate parts, such as triple test cross and correlation, path-coefficient and selection index. The additive and dominance components were found to be highly significant in all the crosses for all the characters. The cross 7(Bm1-20kr × L11-30kr) for seed yield and yield components followed by cross 8 (Bm4-30kr × Bm3) and cross 5(Bm1-25kr × L11-30kr) for some of the yield components may be selected for further breeding research, as they showed moderate to high heritability, additive-dominance inheritance and non-significant epistasis. Correlation, path-coefficient and selection index of thirteen parental lines shows that the lines were genetically well differentiated as indicated by the analysis of variance. In the discriminant function analysis, when individual character was judged separately the highest and positive expected genetic gain was found for SWPP followed by PWPP and PHFF. For selection effective major emphasis should be given on PWPP, PHFF and NBPMF. So, during selection NPdPP, PdWPP and NSPP also be considered because they showed significant positive correlation and positive direct effect on yield.

A selection index was constructed to identify suitable genotypes among the genotypes of lentil following simul- taneous selection model, considering six yield attributes. Lentil ( Lens culinaris Medik.) Diversity, …

under lentil has been declined from 1254760 ha in 1997-98 to 432250 ha in 2007-08 (BBS, 2010). Main concern with lentil is low yield potential because of narrow genetic base of the local cultivars. Therefore, the key to increase lentil yield in South Asia including Bangladesh is through widening the available genetic base (Erskine and
