Sharma, S., Upadhyaya, H. D., Gowda, C. L. L., Kumar, S. and Singh, S. 2013. Genetic analysis for seed size in three crosses of chickpea (Cicer arietinum L.). Can. J. Plant Sci. 93: 387–395. Seed size (determined by 100-seed weight) is an important component of trade and yield in chickpea (Cicer arietinum L.). The present investigation was undertaken to study the possibility of maternal inheritance for seed size and to estimate relative importance of additive and non-additive gene effects on seed size in three chickpea crosses involving two desi (ICC 5002 and ICC 7672) and two kabuli (ICC 11255 and ICC 17109) genotypes. The study included parents, F1, F2, backcross generations, and their reciprocals. Differences in the reciprocal mean 100-seed weight of F1, F2, and backcross generations were not detected in any cross. No definite major gene segregation pattern was observed in the F2 generation, and the continuous variation observed indicated quantitative inheritance. Generation mean analysis indicated the presence of additive gene effects controlling seed size in three crosses. Additive×additive type of non-allelic interactions were found significant in desi×kabuli crosses, ICC 5002×ICC 17109 and ICC 7672×ICC 11255. The selection and breeding procedure may be modified for maximum exploitation of the fixable additive×additive epistasis by delaying selection in later generations and by maintaining large populations prior to selection for maximum recombination of genes to occur.

To determine the association between genetic parameters and morphological traits in chickpea (Cicer arietinum L.) genotypes, a field experiment was conducted with 49 different landrace, breeding lines and cultivated chickpea genotypes using a 7?7 lattice square design with 2 replications in the 2012-2013 growing season. Genetic parameters including genetic, environmental and phenotypic variances; coefficients of variation; heritability; correlation coefficients; factor analysis and path coefficients were estimated, and cluster analysis was performed. High heritability values observed in measured traits indicating that these traits are controlled mainly by additive genes and that selection of such traits may be effective for improving seed yield. Number of seeds per plant, 100-seed weight and plant biomass had a positive direct effect on seed yield. These traits also had positive and highly significant phenotypic correlations with seed yield. Using principal component (PC) analysis, the first three PCs with eigenvalues more than 1 contributed 70.94% of the variability among accessions. The germplasm were grouped into 3 clusters. Each cluster had some specific characteristics of its own and the cluster I was clearly separated from cluster II and III. Overall the results, it can be concluded that seed yield in chickpea can be improved by selecting an ideotype having greater number of seeds per plant, 100-seed weight and plant biomass.

Five lines of cucumber and their 10 F1 diallel crosses were statistically and graphically analyzed to evaluate their performance for eight quantitative traits. Additive and non-additive gene effects were involved in the inheritance of all traits. The variances due ro GCA and SCA effects were highly significant for all traits, but the GCA effect was much greater than SCA except In the case of plant height. The cucumber “TMG-1” and “Yomaki” genotypes were superior for GCA as well as SCA for early and total yields per plant, respectively. Therefore, they can be involved in hybrid programs improvement for cucumber yield under similar conditions.

Genetic diversity study was conducted in 38 chickpea (Cicer arietinum L.) genotypes using Mahalanobis D2 Statistics. The current research performed at FoA, Wadura Sopore, SKUAST-Kashmir in the rabi 2017-18. In the present study, total seven clusters have been formed and range of D2 values is from 301.78 to 8477.71, cluster II includes maximum 12 genotypes after that cluster I having 9 genotypes, cluster IV having 6 genotypes, cluster Ⅲ and Ⅴ having 4 genotypes, cluster Ⅵ having 2 genotypes and cluster Ⅶ with 1 genotype. 959.33 to 8477.71 is the range of inter cluster distance. Highest inter cluster distance (8477.71) was found between the clusters, Ⅵ and Ⅶ followed by the clusters, Ⅳ and Ⅶ (5814.62), Ⅳ and Ⅴ (5807.441), Ⅴ and Ⅵ (4659.34). The minimum inter-cluster distance (959.33) possessed by clusters, Ⅱ and Ⅲ. After comprehending the intra cluster divergence it has been found that cluster Ⅳ has highest intra cluster distance (637.07) then cluster I (459.16). Since cluster Ⅶ includes only one genotype which indicates that there is no intra cluster divergence. Total nine traits have been evaluated, plant height registered higher divergence (49.25%) then pods plant-1 (36.12%), days to 50% flowering (4.13%) and days to maturity (2.7%), secondary branches plant-1 (3.24%), seed yield plant-1 (1.28%) and primary branches plant-1 (1.14%). The 100-seed weight (1.12%) and seeds pod-1 (1.02%) possesses less divergence. By considering above results the nine genotypes viz., IR-1, IR-3, IR-30, IR-20, IR-21, IR-10, IR-2, IR-7 and IR-31 have been recognized as desired genotypes for use in future breeding programme.

The research was carried out to determine selection criteria using correlation and path coefficient analysis in 25 chickpea (Cicer arietinum L.) genotypes under two different environments during rabi 2008-09 at Palampur location. The genotypes showed highly significant differences for all the characters studied in both environments. Environment I (normal sowing) exhibited its excellent potential for the traits viz., seed yield per plant, biological yield per plant, pods per plant, primary branches per plant, days to 50% flowering, days to maturity and plant height, whereas environment II (late sowing) exhibited it for harvest index, per cent crude protein and 100-seed weight. High heritability coupled with high genetic advance was observed for seed yield per plant, pods per plant and 100-seed weight in environment I. Seed yield per plant was positively and significantly correlated with pods per plant (E1=0.767 and E2=0.647), harvest index (E1=0.767 and E2=0.745), biological yield per plant (E1=0.612 and E2=0.537) and primary branches per plant (E1=0.422 and E2=0.515) in both the environments. Path coefficient analysis revealed the high direct effect of biological yield and harvest index towards seed yield per plant, whereas primary branches per plant and pods per plant showed negligible direct effect, but their indirect contribution for it through biological yield and harvest index was high. The present study suggests that selection for high seed yield should be based on selecting high biological yield, pod per plant, high test weight and primary branches per plants in chickpea.

A large seed size in the kabuli chickpea (Cicer arietinum L.) is important in the market not only due to its high price but also for its superior seedling vigor. The double-podded chickpea has a considerable yield and stability advantage over the single-podded chickpea. The study aimed at (i) integrating extra-large-seeded and double-podded traits in the kabuli chickpea, (ii) increasing variation by transgressive segregations and (iii) estimating the heritability of the 100-seed weight along with important agro-morphological traits in F2 and F3 populations. For these objectives, the large-seeded chickpea, Sierra, having a single pod and unifoliolate leaves, was crossed with the small-seeded CA 2969, having double pods and imparipinnate leaves. The inheritance pattern of the extra-large-seeded trait was polygenically controlled by partial dominant alleles. Transgressive segregations were found for all agro-morphological traits. Some progeny with 100-seed weights of ≥55 g and two pods had larger seed sizes than those of the best parents. As outputs of the epistatic effect of the double-podded gene in certain genetic backgrounds, three or more flowers or pods were found in some progeny. Progeny having imparipinnate leaves or two or more pods should be considered in breeding, since they had higher numbers of pods and seeds per plant and seed yields than their counterparts.

Estimates of mean effects, additive, dominance, additive × additive, additive × dominance, and dominance × dominance gene effects were obtained for 15 crosses from 6 inbred lines of corn for each of the following attributes: plant height, kernel row number, ear length, ear diameter, and seed weight.All the gene effects were found to contribute to inheritance of the attributes in the crosses studied. However, not all gene effects are present in all crosses. Mean effects were the most important contributors to the inheritance of the attributes. Of the gene effects, the dominance gene effects were the most important contributors to the inheritance of the attributes except for kernel row number. Additive, dominance and epistatic gene effects appear to contribute more or less equally to the inheritance of kernel row number. Additive gene effects were more important for these attributes than for yield. They were relatively more important for kernel row number, ear diameter, and seed weight than for plant height and ear length.Epistatic gene effects were relatively more important than additive gene effects but less important than dominance gene effects for the material studied. For the attributes studied the additive × dominance and dominance × dominance gene effects were somewhat more important contributors to inheritance than the additive × additive effects.

Twenty two promising Desi chickpea genotypes were grown in RBD with two replications under normal and late sown high temperature conditions with objective to estimate genetic variability for seed yield and its attributing traits to identify potential genotypes for heat tolerance. The maximum genotypic and phenotypic coefficients of variability (GCV and PCV) were observed for number of seeds per pod, 100-seed weight and seed yield per plant under both environments, whereas number of primary branches per plant recorded minimum in late planting conditions. The high heritability coupled with high genetic advance as per cent of mean (GAM) was observed for all traits except days to maturity, plant height and number of pods per plant under both environments but the harvest index recorded moderate heritability coupled with low GAM in late planting conditions. This implies the presence of more additive gene effects for potential crop improvement. On the basis of mean performance for important economic traits under both environments, the genotypes ICCV 92944, Annigeri-1, JG-6, RSG-888, RSG-945 and ICCV-10 were identified as best performer for the number of pods per plant, 100-seed weight, seed yield per plant and harvest index, as well as these genotypes were identified as heat tolerant for the respective traits. The genotype ICCV 10 had stable for yield and yield related traits over both environments, therefore it could be tested over locations for stability verification and for further use in breeding program.

Terminal drought is known to decrease flower production, increase flower and pod abortion, and decrease yield of chickpea (Cicer arietinum L.), but the effects of early-season drought have not been evaluated. The influence of an early transient water deficit on flower and pod production and abortion, and seed yield and its components was evaluated in two chickpea cultivars, Rupali, a desi type, and Almaz, a kabuli type. Thirty-six-day-old plants were subjected to: (i) a transient water deficit by withholding water for 35 days, and then rewatered (WS), and (ii) kept well watered (WW) throughout. In the WS treatment the soil water content, leaf relative water content and leaf photosynthetic rate decreased after water was withheld and, following rewatering, recovered to the WW level. Despite the WS treatment being imposed at different phenological stages in the two cultivars, WS reduced flower number per plant by ~50% in Rupali and Almaz, respectively, compared with the WW plants. In WW plants, ~15% of flowers aborted in both cultivars, and 42 and 67% of the pods aborted in Rupali and Almaz, respectively, whereas in WS plants, 18 and 23% of flowers aborted and 27 and 67% of pods aborted in Rupali and Almaz, respectively. While seed growth in WS plants of Rupali and Almaz occurred primarily after the plants were rewatered, the duration of seed growth decreased by 17 and 36 days, the maximum rate of seed filling increased by 3 times and 5 times, and seed size increased by 26 and 16%, respectively, compared with the WW plants. Seed yield per plant in WS plants decreased by 31% in Rupali and 38% in Almaz compared with the WW controls. The early transient water deficit decreased flower production, but improved flower and pod development; increased the rate of seed growth and increased final seed size; and had a smaller effect on seed yield compared with chickpea subjected to terminal drought.
