“…Based on D 2 analysis, all the genotypes were categorized into seven clusters (Table 1), which indicated a wide range of variation among the genotypes studied. Similar studies were done earlier and reported in brinjal (Sindhuja et al, 2019). In clustering pattern, cluster V accommodated the maximum of 46 genotypes; cluster I housed 30 genotypes; cluster VII had 26 genotypes, cluster IV had 4 genotypes, while each of the clusters namely II, III and VI consisted of two genotypes each and none of the clusters is monogenotypic.…”

Field investigations were carried out during 2019 and 2020 to study the genetic diversity among 112 brinjal genotypes. Mahalanobis's D 2 analysis was done for ten growth and nine yield attributing characters. All 112 genotypes were grouped into seven clusters. Cluster IV (23.975) registered the highest intra cluster distance, whereas cluster II (5.683) recorded the lowest cluster distance. The maximum inter cluster distance was observed for clusters I and IV (24.912). Minimum inter cluster distance was registered between clusters II and III (10.431). Fruit yield per plant, fruit girth and the number of seeds per fruit retained the highest contribution in order towards total divergence. Cluster IV registered the maximum mean for average fruit yield per plant (1647.37). Therefore, the selection of parents from the diverse clusters would yield good segregants for the improvement of yield in brinjal.

“…The intra-cluster distance was observed to be maximum for cluster I (3784.88) (Table 5) pointing out greater heterogeneity of genotypes within the cluster. Similar results were also reported by Sindhuja et al (2019) in brinjal. According to Murty and Arunachalam (1966) the Fig.…”

Genetic divergence analysis in brinjal genetic resources consisting of landraces, related cultivated species and wild relatives based on 22 morphological descriptors revealed distinct variation between cultivated and wild genotypes for the plant, flowering and fruiting characters. The multivariate D 2 analysis grouped the 30 accessions into eight clusters revealing a clear separation of wild relatives and cultivated types. The characters fruit yield per plant, leaf size and fruit number had high contribution towards the genetic divergence. SM-27 (cluster V), SM-25 (cluster III) and SM-23, SM-24,SM-20, SM-18, SM-10 and SM-8 (cluster I) were the promising accessions identified based on superior performance for three yield attributes viz., fruit weight, number of fruits per plant and fruit yield per plant. The accessions SM-25, SM-27, SM-28 (Solanum incanum) and SM-30 (Solanum insanum) of highly divergent clusters III, V and VIII respectively were identified as potential parents for future introgression breeding.

Aim: Brinjal (Solanum melongena L.) is one of the most important vegetable crops which is grown in India and throughout the world which belongs to Solanaceae family with chromosome number 2n =24. This investigation is mainly aimed to evaluate the brinjal genotypes and identify the superior genotypes with high yield, good quality and tolerance to shoot and fruit borer. Study Design: The experimental materials consisted of twenty-one genotypes and two check were laid out in Randomized Block Design (RBD) with two replications. Place and Duration of Research: The study was carried out at Horticulture orchard, Department of Vegetable Science, Horticulture College and research Institute, Tamil Nadu Agricultural University, Coimbatore during 2022-2023. Methodology: In this study, twenty-one genotypes along with two checks were collected from various part of Tamil Nadu. Plants were raised in portrays and 30 days old plants were transplanted to main field at 60 X 60 cm spacing. Growth and yield parameters were observed and recorded. Results: Based on per se performances CBE-SM-006 found to be superior genotype since, it recorded highest marketable fruit yield, number of flowers per cluster, number of fruits per cluster and minimum fruit and shoot borer infestation followed by CBE-SM-108. Hence, CBE-SM-006 and CBE-SM-108 are the promising genotypes which can be used for further breeding programme. Conclusion: The study will provide detail knowledge on selecting the superior genotypes for further crop improvement in brinjal.
