“…Days to maturity, plant production of kernels per day, and shelling percentage do not influence divergence. These findings are in conformity with those reported earlier in groundnut by Vivekananda et al [10]; Niveditha et al [11]; Chavadhari et al…”

Employing the Mahalanobis D2 statistic, a divergence study was performed on 36 groundnut genotypes and 13 clusters were identified. Indicating that the genotypes of these groups may be more divergent from one another, the maximum inter-cluster distance (D) was found between cluster II and cluster XIII (315.56), followed by cluster III and cluster IX (289.56), cluster III and cluster XII (289.21), and cluster XII and cluster XIII (297.11). The genotypes in the mentioned clusters showed a significant difference in the means for traits that contribute significantly to yield, indicating that the genotypes in these clusters make ideal parents in a hybridization programme to produce transgressive segregants and improve groundnut.

“…Compared to other crops, groundnut pods are more pertinent to trait association study because they may make correct selection prior to harvest impossible. But it has been proposed that the environment and/or the genotypes used could affect their estimates (Kiranmai et al, 2016) A successful breeding programme requires the selection of genetically varied parents because it allows for the creation of new, enhanced cultivars with desirable features (Govindaraj, 2015;Niveditha et al, 2016). For the purpose of crop development, cluster and principal component analysis (PCA) are helpful tools for determining the genetic relationships among genotypes.…”

Background: A complex quantitative characteristic, yield is heavily impacted by the environment. The productivity of groundnuts can be increased less effectively through direct selection for grain yield. The study aimed to determine the genetic diversity. Methods: The Mahalanobis D2 statistic was used to quantify the genetic diversity among 24 genotypes of groundnut for seven quantitative and six qualitative criteria. Result: There is sufficient diversity among genotypes, as evidenced by the fact that all of the features in the ANOVA showed significance. High GCV and PCV values were seen for the traits primary-branches/plant (PB), secondary-branches/plant (SB), pod yield/plant (PY), sucrose content (SC), total free aminoacids (TFA), total soluble solids (TSS) and iron content (IC), demonstrating that these traits were well chosen. High heritability and genetic progress as a percentage of mean were observed for plant height, PB, SB, PY, Hundred-pod weight (100-PW), SC, TFA, TSS and IC, demonstrating additive gene-action is in charge of these traits. Twenty-four genotypes were divided into nine clusters using Tocher’s method of clustering, with cluster I being the biggest with sixteen genotypes. Cluster VII and Cluster IX had the greatest inter-cluster distance, which showed that their individuals were more diverse (26.91). In order to obtain transgressive segregants for yield and yield parameters, taking into consideration the cluster distances and cluster means in the current experiment, an emphasis should be focused on establishing crossings between genotypes from clusters VII and VIII that are promising.
