1Chilli (Capsicum annuum L.) is regarded as one of the main commercial vegetable and spice crops at the global level. Maximum diversity can be noted among the cultivars/landraces available in India with respect to shape, size, yield, quality, and other traits. The present experiment was conducted to identify the most promising chilli variety suited for green and dry purposes, to study the genetic variability for different traits and to assess the association of different yield attributing traits with the green and dry yield of chilli. Thirty four genotypes were characterized during a 2-yr period. Most of the genotypes possessed the character constellation of C. annuum. Two genotypes, 'Chaitali Pointed' and 'BC CH Sel-4' were found most promising with respect to green fruit yield (272.79 g, 221.10 g per plant) and dry fruit yield (54.56 g, 44.44 g per plant). Phenotypic and Genotypic Coefficient of Variation values for green fruit weight (119.95%, 111.26%), green fruit girth (89.76%, 48.93%), weight of red ripe fruit (112.02%, 111.93%), weight of dry fruit (111.63%, 110.97%) and number of fruits per plant (86.05%, 85.02%) were recorded to be high. Green fruit yield per plant, ascorbic acid content, and number of fruits per plant also showed very high broad-sense heritability and genetic advance. From the study of correlation and path coefficient analyses, the number of fruits per plant, green fruit length for green chilli, weight of dry fruit and the number of fruits per plant for dry chilli were found to the most important selection indices.
Characterization and Identification of Selection Indices of Pole Type Dolichos Bean
Twelve genotypes of pole type dolichos bean (Lablab purpureus var. typicus) were evaluated for their genetic variability and character association among nine quantitative traits under the Gangetic plains of eastern India. The study revealed significant variation in days to 50% flowering (57-115), length of pod (7.15-15.05 cm), breadth of pod (1.44-3.11 cm), weight of pod (2.92-8.92 g), 100 seed weight (22.2-45.50 g), number of pods/plant (768.3-1897), protein content of pod (0.70-5.45%) and pod yield/plant (5.07-12.21 kg). Genotypes showed differential reaction against Cercospora leaf spot and dolichos yellow mosaic virus. High yielding genotypes generally showed fewer incidences of diseases than the poor yielding genotypes. Characters like number of protein content of pod, number of pods/plant, breadth of pod, weight of pod and pod yield/plant exhibited high GCV, PCV, heritability and genetic advance as percent of mean indicating that such situation may arise due to the action of additive genes controlling the characters. From the correlation and path coefficient analysis, it revealed that the top priority should be given to selection based on the weight of pod, 100 dry seed weight and number of pods per plant for green pod yield improvement and could be considered while formulating selection indices in the improvement of pole type dolichos bean.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
