As a crop for the new millennium Bambara groundnut (Vigna subterranea [L.] Verdc.) considered as leading legumes in the tropical regions due to its versatile advantages. The main intent of this study was to find out the high yielding potential genotypes and considering these genotypes to develop pure lines for commercial cultivation in Malaysia. Considering the 14 qualitative and 27 quantitative traits of fifteen landraces the variation and genetic parameters namely, variability, heritability, genetic advance, characters association, and cluster matrix were determined. ANOVA revealed significant variation for all the agronomic traits (except plant height). Among the accessions, highly significant differences (P ≤ 0.01) were found for almost all the traits excluding fifty percent flowering date, seed length, seed width. The 16 traits out of the 27 quantitative traits had a coefficient of variation (CV) ≥ 20%. A positive and intermediate to perfect highly significant association (r = 0.23 to 1.00; P < 0.00) was found between yield and its related traits. The trait dry seed weight per plant (g) had the highest GCV = 59.91% and PCV = 59.57% whereas the trait fresh pod weight (99.55%), dry seed weight (98.86%), and yield (98.10%) were highly heritable. The genetic advance recorded the highest for dry seed weight (122.01%) and lowest (3.97%) for plant height. To validate the genetic disparity, an unweighted pair-group produce with arithmetic mean (UPGMA), principal component analysis (PCA), heatmap, and H’-index was performed considering 27 quantitative traits. The constructed dendrogram showed five distinct groups of accessions. Genotypes G2, G3, and G9 from Group IV consider as promising lines which gave 70.05% higher mean yield compared to grand mean yield (1180 kg ha−1) with desirable traits. Group II had a maximum number of accessions while group III and group V had one of each. However, findings declared that the availability of genetic variance will be beneficial for this crop improvement through cross breeding as well as the plant breeders to prefer desirable traits in V. subterranea L. Verdc. for further breeding purposes.

Eggplant is an essential widespread year-round fruit vegetable. This study was conducted using 130 local germplasm of brinjal to select diverse parents based on the multiple traits selection index for the future breeding program. This selection was performed focusing on 14 qualitative and 10 quantitative traits variation and genetic parameters namely, phenotypic and genotypic variance (PV and GV) and genotypic and phenotypic coefficients of variation (GCV and PCV), broad-sense heritability (hBS), genetic advance, traits association, genotype by trait biplot (G × T), heatmap analysis and multi-trait index based on factor analysis and genotype-ideotype distance (MGIDI). Descriptive statistics and analysis of variance revealed a wide range of variability for morpho-physiological traits. Estimated hBS for all the measured traits ranged from 10.6% to 93%, indicating that all the traits were highly inheritable. Genetic variances were low to high for most morpho-physiological traits, indicating complex genetic architecture. Yield per plant was significantly correlated with fruit diameter, fruits per plant, percent fruits infestation by brinjal shoot and fruit borer, and fruit weight traits indicating that direct selection based on fruit number and fruit weight might be sufficient for improvement of other traits. The first two principal components (PCs) explained about 81.27% of the total variation among lines for 38 brinjal morpho-physiological traits. Genotype by trait (G×T) biplot revealed superior genotypes with combinations of favorable traits. The average genetic distance was 3.53, ranging from 0.25 to 20.01, indicating high levels of variability among the germplasm. The heat map was also used to know the relationship matrix among all the brinjal genotypes. MGIDI is an appropriate method of selection based on multiple trait information. Based on the fourteen qualitative and ten quantitative traits and evaluation of various genetic parameters, the germplasm G80, G54, G66, and G120 might be considered as best parents for the future breeding program for eggplant improvement.

“…Along with genetic variability, phenotypic variability plays a critical role in tree breeding programs to produce superior trees (Devi et al 2017). Genetic diversity research using genotype-clustering techniques enables quantifying the degree of similarity or diversity among genotypes and thus serves as a valuable tool for breeding improvement in Sicilian chili pepper (Virga et al 2020).…”

Abstract. Al-Amanah H, Sjahril R, Haring F, Riadi M, Larekeng SH. 2021. Mapping distribution of Capsicum annum var. chinense in Tana Toraja and surrounding districts (Indonesia) based on fruit morphology. Biodiversitas 23: 982-991. Katokkon pepper (Capsicum annum var. chinense) is one of the many Capsicum genetic resources still cultivated in small farms and home gardens in Tana Toraja, North Toraja, Enrekang and Mamasa districts of Indonesia. This study was conducted to identify genetic diversity of C. annum var. chinense pepper based on fruit characteristics as morphological markers in the endemic area. The study location was determined by purposive sampling. Morphological characterization was carried out by observing quantitative and qualitative characters. Results showed that C. annum var. chinense was widely distributed in the districts of Tana Toraja 47% (14 sub-districts, 17 villages), North Toraja 34% (11 sub-districts, 14 villages), Enrekang 12% (3 sub-districts, 5 villages), and Mamasa 7% (2 sub-districts, 6 villages). Cluster analysis based on quantitative characters of fruit morphology from 51 accessions led to 5 dendrogram clusters with 90% similarity level. Principal Component Analysis (PCA) results had a cumulative diversity value of 75.913%. The color characteristic of fruit before ripening was light green, which turned red when mature. Cross-sections of the fruits were slightly corrugated. Fruits were pendant, and shapes were blocky. Fruit shape at pedicel attachment was truncated. Fruit shapes at the blossom end were blunt. In all the areas explored, only four common genotypes, i.e. Limbong Sangpolo or Local, Leatung 1, Leatung 2, and Jumbo were found.
