The present research work was carried out at Navsari Agricultural University, Navsari during the rabi-2017 to study correlations among quantitative traits and their direct and indirect effect on pod yield per plant in F2 populations (N1-05-19 x N1-13-465, N1-13-465 x N1-08-203 and N1-05-19 x N1-08-225) of Indian bean. Correlation analysis revealed that, pod yield per plant showed positive and significant correlation with plant height at first picking, branches per plant at first picking, pods per plant, pods per cluster and average pod weight in all the three crosses. This indicated the simultaneous improvement of these characters by selection is possible. Path coefficient analysis revealed that plant height at first picking, pods per plant, average pod weight and fibre content had direct positive effects on pod yield per plant for all the crosses. This indicated that these characters played an important role in expressing high pod yield. Pod length exhibited direct positive effects on pod yield in crosses while, shelling ratio and protein content depicted positive direct effect on pod yield per plant in crosses NI-05-19×NI-13-465 and NI-13-465×NI-08-203, indicating that direct selection for these characters may bring about an overall improvement in the pod yield of Indian bean.
The present study on heterosis and combining ability for fruit yield and its components was carried out in a set of 27 F 1 hybrids of cucumber obtained from a Line x Tester method involving twelve diverse parents at Navsari Agricultural University, Navsari 2009. The ratio of the genetic variance was less than unity, which indicated the predominance of the non- additive gene action in all the traits. The analysis revealed that none of the parents was found good general combiners for all the traits consistently, however parents CCP-9, Gujarat local and SPP-44 were good combiner for fruit yield and its contributing traits. The hybrids Pilibhit Local x K-90 followed by Sheetal x SPP-44 and Sheetal x CC-9 have exhibited higher heterobeltiosis for fruit yield and its components characters. These crosses involved poor x poor and poor x good combiner parents. Further improvement in fruit yield could be possible through the hybridization and selection in transgressive segregants.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
