“…These inherent associations of yield traits with green chilli yield could be attributed to the genetic linkage among the favorable genes for these traits and further the extent of association and co-heritability might depend upon the number of genes involved in a particular trait combination. These results are in accordance with that of Datta and Jana (2010) [8] , Chattopadhyay et al (2011) [6] , Pandiyaraj et al (2017) [19] , Pujar et al (2017) [20] , Sran and Jindal (2019) [25] and Harishkumar et al (2020) [11] . However, the quality trait peroxidase activity was found to be significantly associated with fruit yield per plant in a negative direction.…”

Chilli is one of the most significant vegetable and spice crops globally. Simultaneous selection of a combination of associated characters is always targeted in crop breeding programs. Expression of traits leading to plant phenotype is the result of associated inheritance of many interrelated genes working together. Correlation coefficients were assessed in seventy-two genotypes in chilli for twenty different quantitative characters. Phenotypic correlation co-efficient analysis revealed significant positive association of number of fruits per plant, plant spread in north south, individual fruit weight, stem girth, plant spread in east west, fruit length and plant height with fruit yield per plant. However, the peroxidase activity was found to be negatively and significantly associated with fruit yield per plant. Correlations among yield component traits revealed positive and significant association of individual fruit weight with fruit diameter, fruit length, whereas showed negative significant relation with number of fruits per plant. Plant spread in east west direction and north south, plant height and stem girth had significant positive association with number of fruits per plant. Among the quality parameters, the trait capsaicin content had positive and highly significant correlation with fruit diameter and individual fruit weight, but negative with dry matter content, Ascorbic acid and stem girth.

Chilli (Capsicum annuum L.) cultivar share a variety of different and intriguing growth and yield characteristics, for a plant breeder studies on genotypic and phenotypic relationship for horticulture cum vegetable spicy crop and its traits are useful to design, evaluate and to develop selection criteria for desired traits. With this background information the present study focused on identification of crucial characteristics required for boosting yield and to determine the parameters for the selection of superior genotypes. A total of 30 chilli genotypes were subjected to variability, divergence and mutual correlation studies for yield and yield component traits by using multivariate analysis. Results from the analysis of variance and variability revealed highly significant differences at (p≤0.01) and (p≤0.05) for all the studied traits. The highest genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) were observed for FL fallowed by FYP, NFP, IFW, WPDM, FD, PH and NSF respectively, except for MC has revealed low GCV and PCV. All the traits were shown the presence of high heritability ( ) in broad sense (>60%) coupled with high GAM (>20%), except for MC, indicating the presence of positive additive gene action and effective transmission of characters to the next generation with selection. Highly significant and positive strong correlation was observed for IFW (r = 0.68**), WPDM (r = 0.54**), TW (r = 0.40*) and FD (r = 0.37*) with FYP, while the path analysis revealed highest direct effect for the traits such as FPT, FL and NFP. Principle component analysis revealed a 70.60% total variation accounted with first four PCAs with Eigen vector values more than one. Further cluster analysis grouped the 30 chilli genotypes into four major cluster (Cluster I, II, III and IV) and combined cluster analysis identified genotypes contributing to the maximum variability, viz., cultivars such as LIPSTICK, B.KADDI, B.DABBI, BHOOT JALOKIA, SUM- 17, BCH- 42, PBC- 80, LCA- 310, M- 262, KA2- L, S. SELECTION 1, JCH- 42 and 9608- U, so these genotypes serves as a donor for further breeding programme to develop superior cultivars.

“…For the traits No. of fruits plant -1 and fruit weight, the results are in conformity with Sran and Jindal (2019). High heritability along with high genetic advance reported for these traits provide good scope for further improvement in advance generation if subjected to mass progeny or family selection.…”

“…Plant breeding programs focus on increasing crop yield in a wide range of growing conditions (Saidaiah et al, 2021a). Hence new genotypes must be characterized to assess the variability and identify promising genotypes which can be used in further breeding programmes (Munshi et al, 2000;Sarma and Roy, 1995, Sreelathakumary and Rajamony, 2004, Pidigam et al, 2021. Therefore, identification and utilization of diverse genotypes is essential for breeding new cultivars in a desired direction (Aparna et al, 2014).…”

Thirty five chilli genotypes were evaluated in a randomized block design at College of Horticulture, Rajendranagar, Sri Konda Laxman Telangana State Horticultural University, Hyderabad, Telangana state, India during Kharif, 2019 for seven months and at National Bureau of Plant Genetic Resources, Regional station, Rajendranagar, Hyderabad during Rabi 2019-20 for seven months to estimate genetic variability, heritability, genetic advance and genetic advance as % of mean of seventeen yield and yield related traits. For all the traits studied, the magnitude of PCV was higher than corresponding GCV. High Phenotypic coefficient of variation and genotypic coefficient of variation estimates were recorded for plant height, plant spread, fruit length, fruit diameter, number of fruits plant-1, fruit weight, fruit yield plant-1, fruit yield plot-1, ascorbic acid, capsaicin content and capsanthin content indicating the existence of wider genetic variability for these traits in the genotypes studied. High heritability was recorded for the traits Days to first flowering, Fruit length, Fruit diameter, No. of fruits plant-1, Fruit weight, Fruit yield plant-1, Fruit yield plot-1, Ascorbic acid, Chlorophyll content, Capsaicin content and Capsanthin content. High heritability coupled with high genetic advance as % mean indicates existence of additive gene action which was observed in fruit length, fruit diameter, number of fruits plant-1, fruit weight, fruit yield plant-1, fruit yield plot-1, ascorbic acid, chlorophyll content, capsaicin content and capsanthin content. Hence these traits can be improved by direct selection.
