Dissecting heterosis architecture in lentil Rathi A. S., Kumar R. Department of Genetics and Plant Breeding, C.S.A. University of Agriculture and Technology, Kanpur-208002 Online published on 20 September, 2012. Abstract Five best yielding hybrids among 90 F1 of lentill were evaluated for its 9 component traits to understand the basis of heterosis for yield. Hybrids exhibiting positively singnificant heterosis for all the 9 traits excelled maximun, heterosis (144.7%) for yield, while hybrids showing negative heterosis for either test weight or pods per cluster, showed it decline of 21.24% heterosis in Yield, and if heterosis is negative for both the traits, 35% decline occurs in yield. It was asserted that heterosis for, yield has positive association with vigours of its component traits like test weight and pods per clusters. Top Keywords Heterosis, lentil, yield component.
