Combining Ability Analysis

Combining ability analysis has an important position in rapeseed breeding. To evaluate genetic and combining ability effects, three Brassica napus L. testers “Punjab Sarson, Legend and Durre-NIFA” and five lines “Duncled, K-258, ZN-R-1, ZN-R-8, ZN-M-6” were crossed using line × tester design in Randomized Complete Block Design (RCBD) with three replications. Mean sum of squares of the analysis of variances (ANOVA) for genotypes was highly significant for all of the traits. Most of the lines and testers exhibited significant results of mean sum of squares for combining ability. Line ‘Duncled’ was proved good general combiner for oil (8.8), protein (3.7), erucic acid (33.0), oleic acid (13.0) and glucosinolate (-19.3) over other lines and tester ‘Durree-NIFA’ for protein (6.6), erucic acid (-23.4), and linolenic acid (-5.3) over other testers. Significant specific combining ability effects were also observed. The best hybrid combinations were Legend × ZN-R-1 for oil (9.6), Punjab Sarson × Duncled for minimum erucic acid (-14.0) and linolenic acid contents (-6.0), and Legend × ZN-M-6 for maximum protein (8.2) and minimum glucosinolate contents (-11.1). The maximum oil contents were observed in ‘Legend × ZN-R-1’ (52.4%). The cross ‘Punjab Sarson × Duncled’ expressed maximum values of protein (26.5%) and oleic acid (62.5%) while minimum for erucic acid (2.3%), linolenic acid (5.4%) and glucosinolate contents (19.3µmol/g). This research discloses the significance of non-additive genetic effects for most of the studied traits except oil contents. These studies will also help to improve nutritional values of rapeseed crop by selecting noble crosses.

Winter Rapeseed

Combining ability (CA) of lines is one of the main criteria of estimation of the parental components of hybrids. There are existed the different crossing schemes for estimation of a combining ability. A method of top-cross is successfully used in a breeding practice. This method was used for estimation of a range of new CMS-lines of winter rapeseed perspective in breeding of simple interline hybrids. In our research we used six sterile lines on a base of CMS Ogura and six lines-restorers of fertility (testers). We obtained 36 test-hybrids for estimation of a combining ability of the lines. Positive combination of effects of the general combining ability (GCA) and variances of the specific combining ability (SCA), stable manifested in two years, we observed in two maternal lines 39712 and 40059. Hybrids with these lines had the higher average seed yield in two years of the research. These lines can be recommended for development of practically important hybrids of winter rapeseed. It is considered the testers possessing high GCA are promising for estimation of lines CA. in our research, two lines ORK 9 and ORK 21 demonstrated the high average seed yield of test-hybrids in two years of the research and can be recommended for usage as testers.
