“…Thus these genotypes may be used in the future hybridization programme to get diverse sergeants in the improvement of cluster bean genotypes. These findings were supported by Padmavathi et al (2021) and Khatoon et al (2023).…”

“…The inter cluster distance estimated highest between cluster I and II (32.146), followed by between cluster I and III (31.006) and between cluster II and III (22.807), indicating the presence of broad divergence among the genotypes present in these clusters, therefore genotypes present in these cluster could be utilized as a parent for varietal development. These findings were supported by (Khatoon et al, 2023).…”

“…Fifth principal component (PC 5) attributed 8.56% of total variance by the major contributor PL. Similarly, first three principal components contributed more than 75% of the total variation with eigen value greater than one in Khatoon et al (2023). The cos 2 (squared cosines or squared coordinates) values are used to estimate the quality of representation of the variables on factor map.…”

Background: Twenty six genotypes of cluster bean [Cyamopsis tetragonoloba (L.) Taub] were evaluated under randomized block design with three replications under the field condition to estimate the range of variability and diversity present in cluster bean genotypes for fifteen yield and yield contributing traits. Methods: The experiment was carried out at Research Farm, Department of Genetics and Plant Breeding, N. M. College of Agriculture, Navsari Agricultural University, Navsari, Gujarat in the year 2020 on twenty-six genotypes of cluster bean. Result: Correlation coefficients of fifteen traits estimates indicated positive and highly significant correlation of seed yield per plant with pods per plant, pods per cluster, pod yield per plant and seeds per plant, so these characters should be considered for selection for increasing yield in cluster bean. Gum content was negatively and significantly correlated with days to 50% flowering, seed yield per plant and 100 seed weight at genotypic level hence, selection for gum content might not be desirable for test seed weight and seed yield. Principal component analysis revealed significant variation among traits evaluated with the five principal components explaining approximately the 75.8% of the total variation with ³1 eigen values. Most of the variation contributed by the pods per cluster, pods per plant, gum content, pod yield per plant and seed yield per plant, these traits should be considered while selecting the cluster bean genotypes. The PCA- biplot revealed GAUG-1305, GG-1801, RGC-936 and RGC-986 as the most diverse genotypes for various traits. Cluster analysis distributed 26 cluster bean genotypes into three different clusters by UPGMA method. In the present investigation, the genotype GAUG-1305 recorded higher pods per plant, while GAUG-1502 for higher pod yield per plant, the genotype RGC-1003 for high pod length and RGC-936 exhibited higher pods per cluster, seeds per pod and seed yield per plant. So, these genotypes could be used in the future breeding programs.

“…PCA can convert the original number of indicators that are related to one another into new global indicators that are less numerous and independent of one another, with little or no loss of original information [34]. PCA has been used to conduct a comprehensive assessment in peanut germplasm resources [26,55,65]. There were three new factors that were extracted following PCA in this study (Figure 5), which were yield and its constraints, the early flowering process, and the fullness of the seed.…”

Peanut is a leguminous crop with an indeterminate growth habit that will continuously flower during the entire reproductive development stage. Flowering redundancy adversely affects the yield and quality of peanut. In this study, eight flowering and five yield-related traits were collected and comprehensively evaluated from a diverse germplasm panel consisting of 232 peanut accessions, aiming to provide a theoretical basis for improving the flowering habit and yield for future peanut breeding efforts. As a result, large phenotypic diversity was observed in 13 traits. Most of the traits suggested high heritability, except high effective flowering duration (HEFD), days to 100% flower cessation (DTC100), and yield per plant (YPP). Days to 90% flower cessation (DTC90), days to DTC100, flowering duration (FD), and low effective flowering duration (LEFD) showed significant negative correlations with 100-seed weight, 100-pod weight, YPP, average weight per pod, and shelling percentage. Principal component analysis (PCA) suggested that flowering redundancy traits as well as yield-related traits contributed more to the first three PCs when compared to other traits. This study addresses the lack of peanut flowering phenotypic and genetic diversity and lays the foundation for in-depth research on redundancy-related genes in peanut flowering.
