dc.description.abstract | A total of 14 medium duration genotypes of Pigeonpeawere taken up for study, evaluation, and for characterization for the present investigation in two different environmental conditions (Environment I and Environment II). The entries consisted of six genotypes of F6 generation with negligible segregation along with three national checks BDN-2, JKM-189, ASHA and one local check BA-1, with two multi-resistant (Wilt and SMD resistance) checks BSMR-736 and BSMR-853 and two highly susceptible checks MARUTI for susceptibility to Sterility Mosaic Disease and ICP 2376 for susceptibility to FusariumWilt. The different mean data recorded of each genotype or treatments along with the checks or control was subjected to statistical analysis for variance, covariance, heritability, genetic advance, correlation and path analysis, to find out the individual as well as the combined comparative effects of each treatment on each other. The GCV & PCV were recorded highest for the character number of secondary branches, final plant stands, 100 seed weight, initial plant stands, 100 seed weight, and number of pods per plant in both the environmental conditions. In both the environmental condition characters such as wilt incidences, final plant stands, number of secondary branches, initial plant stands, and 100 seed weight were recorded to have high heritability and high genetic advances which indicates that the selection would be effective and that these characters have dominance of additive gene action in their expression. highly significant and positive correlation (both phenotypic and genotypic level) was found between the yield and the characters like number of primary branches, number of secondary branches, number of pods per plant, final plant stands, number of seeds per pod,100 seed weight and with harvest index also in Environment I it was found that the a positive and highly significant correlation was observed between yield and the characters such as initial plant stands, number of primary branches, number of secondary branches, plant height number of pods per plant, final plant stands, pod size, and 100 seed weight and with harvest index. The incidences of wilt were recorded to be of higher magnitudes in Environment II (Wilt testing plot) than in the Environment-I (field condition). Wilt incidences was found to be negatively and highly correlated with the yield and directly affected the yield in both negative and positive direction. Whereas the incidences of Sterility Mosaic Disease and Pod Borer were found to be nonsignificantly correlated with the yield and had negligible indirect effect on the yield. Expression of secondary branches was higher in case of genotypes BAUPP 19-6 also having maximum number of primary branches under sick plot and genotype ICPL 87119 under natural condition. BA-1 was found to be the tallest among all the genotypes under study in two different environments. The genotypes BAUPP19-6 had the highest number of pods per plant under sick plot condition and best check was found to be BA-1 that had the highest number of pods in both the environment. On the basis of the statistical analysis and the comparison of the mean values of all the genotypes it was significantly recognized that the genotype BAUPP19-6 had highest yield under in both the environmental conditions followed by BAUPP19-4 and BAUPP19-3. | en_US |
