“…These parents can be included in breeding progamme for yield improvement. Similar findings had also been reported by Singh et al (2005), Singh et al (2013) and Meena et al (2015) in Indian mustard with different set of materials. A total of six crosses, viz.…”

“…The crosses with positive SCA effect for seed yield/plant also showed significant positive SCA effects for other yield contributing traits like, number of primary branches, number of secondary branches, number of siliquae on main shoot, siliqua length and 1000-seed weight. High SCA effects for seed yield/plant using line × tester analysis had also been reported earlier (Yadava et al 2012, Singh et al 2013.…”

“…The heterosis breeding needs testing of the genetic value of parental lines for production of superior recombinants. The line × tester mating design (Kempthorne 1957) has been extensively used in Indian mustard to analyze the combining ability effects and to provide information regarding genetic mechanisms controlling seed yield and yield attributing traits (Parmar et al 2011, Yadava et al 2012, Singh et al 2013, Meena et al 2015. Knowledge of gene action and estimation of general and specific combining ability effects (GCA and SCA) are important parameters, as they provide an essential tool to the breeders in selection of better parental combinations for further improvement in rapeseed-mustard crops.…”

Indian mustard [Brassica juncea (L) Czern. and Coss.] is an important oilseed crop which occupies leading position in oilseed sector of Indian agriculture. Development of high yielding genotypes with high oil content in Indian mustard has been a major breeding objective owing to high edible oil import in India. Present study was conducted with a set of 53 genotypes, that included 40 crosses and 13 parents evaluated for pooled estimation of combining ability and heterosis for yield and yield attributing traits during rabi 2014-15 under timely sown, late sown and extra late sown environmental conditions. The crosses were developed in line × tester design involving 8 lines and 5 testers during rabi 2013-14. The genotype × environment interaction was significant for almost all the traits studied indicating differential response of genotypes to the change in environments. The pooled analysis of variance over environments revealed sufficient differences among environments, parents, hybrids and parent vs. hybrids for most of the traits studied. Importance of both additive and non-additive types of gene actions was observed for seed yield and yield attributing traits. Estimates of GCA effects indicated that NRCHB-101, Pusa Bold and RGN-73 were good general combiners for seed yield/plant and yield attributing traits, i.e. 1000-seed weight, siliqua length, number of primary branches and number of secondary branches. The parent, Pusa Mustard-25 showed good combining ability for dwarfness and early maturity. The hybrids, viz. NRCHB-101 × EC552577, NRCHB-101 × BPR543-2, Pusa Mustard-25 × EC552577, BAUM-2007 × EC552577 and BAUSM 92-1-1 × RGN-73 had significantly high SCA effects, >15% heterobeltiosis and high per se performances for seed yield per plant. The parents showing good combining ability would be identified as promising genotypes and the hybrids having high SCA effects with high heterobeltiosis could give transgressive segregants for seed yield and yield attributing traits under different sowing conditions.

“…Brassica juncea is a crop of Asiatic origin with its major centre of diversity in China from where it was introduced in India (Vaughan, 1977). It is the second important oilseed crop at national level and contributes nearly 27% of edible oil pool of the country (Singh et al, 2013). It is a naturally autogamous species Article History…”

In the present study, line× tester analysis was carried out at Castor-Mustard Research Station, S. D. Agricultural University, Sardarkrushinagar, Gujarat, India during rabi 2018–19 (October 2018 to February 2019) in order to estimate all three types of heterosis (relative heterosis, heterobeltiosis and economic heterosis) for identification of superior cross combinations of Indian mustard [Brassica juncea (L.) Czern&Coss]. Thirty-five hybrids along with five CMS lines, seven testers and check GDM 4 were evaluated for ten different traits. The F1 generation of all the crosses exhibited fertility restoration with pollen fertility except F1 crosses with Vardan, Rohini and SKM 319 fertile line (0%). The remaining crosses exhibited pollen fertility ranging from 68.26% (Kranti×SKM 303) to 85.17% (Kranti×Mori ‘R’ 1-18). The analysis of variance for parents, hybrids and parents vs. hybrids revealed that mean sum of squares of parents were highly significant for majority of the characters except days to maturity. Whereas, hybrids differed highly significant for all the characters. Comparison of mean squares due to parents vs. hybrids was found significant for almost all the characters except number of seeds siliqua-1 and oil content. This indicates that considerable amount of genetic variability present among the parents and hybrids for all the characters studied. On the basis of per se performance, three hybrids viz., Kranti×Mori ‘R’ 1-18, SKM 9928×PusaAgrani and SKM 9928×Mori ‘R’ 1-18 were foundpromising for seed yield plant-1 over the standard check GDM 4.With respect to heterosis, one of the hybrid Kranti×Mori ‘R’ 1-18 (17.85 %)manifested significant and positive standard heterosis for seed yield plant-1.

“…Its oil cake is rich in protein but due to its high glucosinolate content it is not suitable for animal feed. Combining ability analysis is one of the powerful tools to test the value of parental lines to produce superior hybrids and valuable recombinants (Singh et al, 2013) [10] . Further, for developing better genotypes through hybridization, the choice of suitable parents is of great concern.…”

The experimental material comprised of fifty six genotypes consisting of six cytoplasmic male sterile lines (GM 1 Ogura, GM 2 Ogura, GM 2 Oxyrrhina, GM 1 Siffolia, GM 2 Siffolia and GM 1 Mori) and seven fertile lines (GM 3, SKM 149, SKM 303, RSK 88, RSK 95 and RSK 96) crossed in line × tester mating design. The resultant forty two hybrids along with their thirteen parents and standard check (NRCHB 506) were evaluated in randomized block design at Castor-Mustard Research Station, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar (Gujarat) during rabi 2020-2021. The analysis of variance for parents, hybrids and parents vs. hybrids revealed that mean sum of squares of parents were highly significant for majority of the traits except siliqua length. Whereas, hybrids differed highly significant for all the characters. The ratio of σ2gca/ σ2sca was found less than unity for the traits viz., days to maturity, total number of branch per plant, total number of siliqua per plant, siliqua length, number of seeds per siliqua, seed yield per plant, 1000 seed weight and oil content which suggested the greater role of non-additive gene action for the inheritance for these traits. Among the parents, female GM 1 Mori was good general combiner for seed yield per plant, total number of siliqua per plant and 1000 seed weight and GM 1 Ogura was good general combiner for seed yield, total number of branch per plant and total number of siliqua per plant. Whereas, male parent RSK 88 was good general combiner for seed yield per plant, total number of branch per plant, total number of siliqua per plant, siliqua length, number of seeds per siliqua, 1000 seed weight and oil content. Best three hybrids which possessed significant positive SCA effects for seed yield per plant over standard check NRCHB 506 (12.20 g) were GM 1 Ogura × RSK 88 (21.41 g), GM 2 Oxyrrhina × SKM 303 (20.37 g) and GM 1 Siffolia × RSK 88 (19.95 g).
