Abstract:

The present investigation was carried out to study the mean performance, heterosis, combining ability and gene action for different seed traits viz., seed germination, seed vigour index-I, seed vigour index-II and fruit yield in 15 F1 crosses, developed by crossing 6 genotypes during the year 2015. The seeds of all parents and their crosses, along with standard check (KH-1) were assessed for different seed traits (under laboratory conditions) and fruit yield (under open field conditions) during the year 2016. Experimental results revealed that genotypes PI-618860, Khira-75, UHF-CUC-1 and UHF-CUC-2 were found superior on the basis of mean performance, heterosis and general combining ability studies. The cross combinations viz., Khira-75 x PI-618860, Khira-75 x UHF-CUC-1, Khira-75 x UHF-CUC-2 and Khira-75 x PI-618860, UHF-CUC-1 x PI-618860, UHF-CUC-3 x Poinsette, UHF-CUC-3 x PI-618860 were found best on the basis of mean performance, heterosis and specific combining ability studies respectively. Further, Gene action studies indicated the predominant role of non-additive gene action for the control of all the traits under study; hence heterosis breeding can be utilized for the genetic improvement of seed vigour and yield traits in cucumber.


Keywords: Combining ability, Gene action, Heterosis, Seed germination, Seed vigour index-I and II.
