Quantitative And Qualitative Traits

Combining ability analysis was performed in a 10× 10 half dialle cross in Indian mustard genotypes for yield and quality traitsduring 2017-18 and 2018-19 at the agriculture research farm R.B.(PG) college Mudi, Agra and IFTM university,Lodhipur Rajput Moradabad.In this study, 45 F1 hybrid and their parents were evaluated for 14 quantitative and qualitative traits. The parents used namely, NRCHB -101, DRMR- IJ- 31, Kanti, Urvashi, Pusa mustard- 25 (NPJ-112), Pusa mustard-26 (NPJ-113), Pusa mustard- 27 (EJ-17), CS- 54, RH- 406, RH -749. The results indicated that both additive and non-additive type of gene actions were responsible in expression of all the 14 characters. Parental genotypes viz., RH -749, RH -406 and CS -54, showed high GCA effects for seed yield per plant and most of the important characters except days to 50% flowering and days to maturity. The other parent’survashi, PM -27, DRMRIJ- 31, NRCHB -101 showed high GCA effects for the remainingtraits. Out of 45 crosses only three crosses RH- 406 × RH -749, PM- 26 × RH -406 and PM -26 × RH -406 had desirable and significant SCA effects with high per se performance for seed yield per plant in F1,s generation. The present study indicated that genetic improvement in the Indian mustard would be achieved by using selected promising crosses having significantly high SCA values coupled with high per se performances.

Hybridization Programme

Combining ability analysis revealed that good general combiners were Urvashi x KMR-15-2, Pusa Agrani x Pusa Bahar, RH-749 x Pusa Bahar, RH-749 x Durgamani and KMR-15-2 x Pusa Bahar were best specific combiners for seed yield per plant. In hybrid high heterosis over better and mid parent Urvashi x KMR-15-2, Pusa Agrani x Durgamani, RH-749 x KMR-15-2, KMR-15-2 x Pusa Bahar and KMR-15-2 x Durgamani and Urvashi x KMR-15-2, Pusa Agrani x Pusa Bahar, RH-749 x Pusa Bahar, KMR-15-2 x Pusa Bahar and KMR-15-2 x Durgamani, respectively and high x high general combiners with significant sca effects for seed yield per plant. The parents namely, Urvashi, KMR-15-2, Pusa Agrani, Pusa Bahar, RH-749, Pusa Bahar, RH-749, Durgamani, KMR-15-2 and Pusa Bahar were good general combiners for number of traits and hence, may be used further in hybridization programme. Developmental attributes likes days to flowering, days to maturity, number of siliquae per plant and oil content, 1000-seed weight, seed yield per plant should be given maximum frequency for getting higher productivity in Indian mustard.

Three CGMS lines were crossed with 17 testers in a line × tester design during Kharif 2013 and sufficient number of hand pollinated seeds was produced. The resultant 51 hybrids along with their 20 parents and standard check variety (Maruti) were evaluated in RBD design with two replications. Combining ability analysis evinced predominance of non-additive gene effects for 7 characters indicating relevance of heterosis breeding for improving yield attributes. The gca effects of parents revealed that ICPA-2043, GRG-2009, GRG-2009-2, LAXMI, LRG-41 and JKM-197 were good general combiners for seed yield and it’s direct components. The estimates of sca effects revealed that 11 experimental hybrids had significant, desirable and positive sca effects for seed yield/plant. Among these, three best crosses were selected on the basis of per se performance for ascertaining their association with sca effects of seed yield per plant and its attributes. The investigation identified the good general combiners (ICPA -2043, GRG-2009, GRG-2009-2, LAXMI, LRG-41 and JKM-197) and promising crosses (ICPA-2043 X GRG-2009-2, ICPA-2047 X GRG-2OO9 and ICPA-2043 X ICPL-288) showing high mean and significant positive sca effects involved high × high gca effects of parents. These parental combinations may be used in breeding program for exploitation of hybrid vigour.

Combining ability analysis for yield and yield components of mungbean [Vigna radiata (L.) Wilczek] was attempted using an 8 x 8 diallel mating system both in F1 and F2 generations. Both gca and sca mean squares were significant for all the eleven characters in F1 and F2 generations, former being more pronounced for clusters per plant, pods per cluster, pods per plant, pod length, seeds per pod, 100-seed weight and seed yield per plant in F1 and for all the characters except days to maturity, seeds per pod and 100-seed weight in F2. The parent K 851 was a good general combiner for seed yield per plant, days to maturity, plant height, primary branches per plant, clusters per plant, pods per plant and seeds per pod in both generations, while Pant-M 4 was good general combiner for seed yield per plant, plant height, pods per cluster and pods per plant over generations. Parents RMG 62 and Asha were the best combiners for early flowering. GM 4 had good general combining ability for seed yield in F1, but for pod length and 100-seed weight in F1 and F2. The crosses showing high sca effects for seed yield also had significant and positive effects for at least two important yield components.

Line × tester analysis of twenty lines and three testers of Indian mustard (Brassica juncea L. Czern & Coss.) cultivars were used to estimate general combining ability (GCA), specific combining ability (SCA) effects, high parent heterosis and narrow-sense heritability estimate for plant height, yield components and seed yield. Significant variance of line x tester for the traits like pods per plant and seed yield indicating non additive genetic effects have important role for controlling these traits. Significant mean squares of parents v/s crosses which are indicating significant average heterosis were also significant for all the traits except seeds per pod. High narrow-sense heritability estimates for all the traits except seeds per pod exhibited the prime importance of additive genetic effects for these traits except seeds per pod. Most of the crosses with negative SCA effect for plant height had at least one parent with significant negative or negative GCA effect for this trait. For most of the traits except pods per plant, the efficiency of high parent heterosis effect was more than SCA effect for determining superior cross combinations.

SUMMARYTo develop an effective breeding programme for rainfed production of the common bean (Phaseolus vulgaris L.), the inheritance of seed yield under such conditions should be understood, preferably considering the effects of environment to account for site or season specificity. Thus, heritability, expected and realized gain from selection, and combining ability were evaluated for a nine-parent diallel of common bean without reciprocals but including parents, at two locations each in Mexico and Colombia, using the F2 and F3 population bulks. Heritability estimated from regressions of F3 on F2 ranged from 0·09 ± 0·18 (S.E.) to 0·75±0·25 for seed yield, from 0·26±009 to 0·34±009 for days to maturity and from0·57±004 to 0·80±004 for 100-seed weight. Expected gain from selection in the F2 was estimated as a percentage of the population mean, selecting the upper 20% of the populations. Expected gain in seed yield ranged from 1·8 to 8·4% in Mexico and from 6·5 to 28·1% in Colombia. Realized gains in seed yield in the F3 were 0·4–7·4% in Mexico and 2·9–15·7% in Colombia. Realized gain values for days to maturity were < 2·2%, and for 100-seed weight > 13·4%. General combining ability (GCA) mean squares (estimated using Griffing's Method 2, Model 1) were significant (P <0·01) and larger than those for specific combining ability (SCA) for all traits at all locations. The parents from the Mexican highlands tended to have a positive GCA effect for yield in Mexico but negative values in Colombia, whereas parents adapted to mid-elevation tropical environments showed the opposite tendency. However, all significant GCA values of breeding line V8025 were positive in both countries.
