Comparing of Self-Incompatibility and Cytoplasmic Male Sterility Systems for the performance of F1 hybrids in cabbage (Brassica oleracea var. capitata L.)
Abstract
Four cytoplasmic male sterile (CMS) and three self-incompatible (SI) lines of cabbage were used as females for crossing with four cabbage testers (males) as per line × tester mating design during 2012-13 to produce the F1 seeds of 28 hybrids. These hybrids were evaluated in Randomized Block Design with two standard checks Varun and KGMR-1 at the Vegetable Research Farm, CSKHPKV Palampur (mid-hills, sub-temperate with high rainfall) during 2013-14. Based on the performance, the hybrids CMS GAP x E-1-3 and II-12-4-10 x SC 2008-09 were either at par with the standard check 1 (Varun) and standard check 2 (KGMR-1) or significantly superior to both the checks for marketable head yield and most of the component traits. The hybrids which involved CMS lines as one of the parents have excelled in their performance for majority of the characters viz., plant spread, non-wrapper leaves, polar diameter, days to harvest, head shape index and head compactness, whereas for the characters viz., gross head weight, net head weight, equatorial diameter and marketable head yield per plot the hybrids developed using SI system excelled. Among the top five hybrids, four were of CMS system and one was of SI system. So, CMS system was considered more effective for production of F1 hybrids by using the genetic material used in this study.
