“…Concerning the number of branches, we observed a range of 2.42 (genotypes K696 (corniform) and K1056 (pumpkin shape)) to 3.25 (K712 (pumpkin shape)). Our results corroborate an earlier study [33]; however, the latter reported larger variation in the number of branches (2.3 to 5.3) than we observed. Concerning productivity, K1115 (pumpkin shape) and K1112 (blocky) were the most and least productive accessions, with 0.74 kg per plant and 0.46 kg per plant, respectively (Table 2).…”

To maintain the continuous genetic variation and increase the genetic gain, appreciable germplasm diversity and its comprehensive characterization is necessary to further utilize gene sources for pre-breeding. The diversity of pepper forms, cultivation traditions and diverse fruit usages are typical for Balkan countries. Considering this rich diversity, 21 pepper accessions from the Balkan region were evaluated for morphological, biochemical, and insect resistance traits during 2018 and 2019 at Maritsa Vegetable Crops Research Institute, Plovdiv, Bulgaria. Among the studied accessions, the highest productivity was observed in pumpkin shape K1115 and kapia type K1081 accessions, with 0.74 kg and 0.70 kg per plant, respectively. Concerning fruit quality, the highest total polyphenols and ferric reducing antioxidant power (FRAP) were observed in pumpkin shape K712 (203.44 mg GAE/100 g FW) and K1103A (11.49 µmol Fe2+/g FW) accessions, respectively. Concerning insect resistance, 38% of studied accessions showed no infestation of green peach aphid. The kapia type K697 accession was seen as the most reliable resistance source, as it was not infested by aphids and had the least thrips (20% on plants) and cotton bollworm (6.67% on plants and 8.34% on fruit) damage. Based on examined traits, accessions were identified for enhanced fruit quality and promising insect resistance and have been included in further pre-breeding efforts.

“…Fruit diameter variability was found in T-5 Arka Sanvi hybrid cultivar (1.107 cm) followed by T-7.H25 hybrid cultivar (1.088 C cm) and minimum fruit diameter was observed in in the treatments in check T8 (0.985 cm). Similar results were obtained Janaki et al, (2015) [7] . Performance of chilli genotypes for yield and yield attributing traits.…”

The present investigation entitled, Evaluation of Chilli F1 hybrid cultivars (capsicum annum L.) chilli F1 hybrid suitable for green and dry chilli market under zone Southern zone of Karnataka. Eight chilli F1 hybrid cultivar where evaluated during the year kharif 2021 at Agricultural & Horticultural Research Station, Katahalagere (Davangere district). The Chilli F1 hybrid cultivar were collected from I I H R. Bangaloru eight cultivars.

“…The maximum inter-cluster distance was noted between IV and VI clusters (1588.27) followed by I and VI clusters (1526.21). The hybrids of diversified genotypes were better yielders according to (Kumar et al, 2010;Janaki et al, 2015;Udachappa et al, 2017;Sindhusha and Monisha, 2020). Hence, crossing between the genotypes from IV (PKMCA-07) and VI clusters (PKMCA-37) could be expected better hybrids and to attain maximum heterosis along with desirable segregants.…”

Genetic diversity among forty-seven genotypes of Mundu chilli (Capsicum annuum L.) was assessed for fifteen yield and quality characters during kharif 2018. The analysis of variance disclosed that significant difference present for most of the parameters studied, which indicated the existence of wide diversity among all Mundu chilli genotypes. Mahalanobis D 2 statistic stated that the forty-seven genotypes were grouped into six clusters. The highest contribution for genetic divergence was dry fruit yield per plant (25.7%), Ascorbic acid (11.56%), 1000 seed weight (10.85%) and the number of seeds per fruit (10.5%). Among the clusters, the largest was cluster II containing 21 genotypes followed by cluster III (13 genotypes) and cluster I (10 genotypes) whereas, clusters IV, V and VI were grouped as solitary clusters (one genotype in each cluster). The highest inter-cluster distance was noted between clusters IV and VI (1588.27) whereas, the lowest was recorded between clusters II and V (192.44). Cluster III (144.94) has recorded the highest intra-cluster distance and the lowest was observed in clusters IV, V and VI (0.00). D 2 cluster analysis revealed wide genetic distance (inter-cluster) between the genotypes of cluster I (PKMCA-38), II (PKMCA-20, PKMCA-32, PKMCA-33) and V (PKMCA-08). Hence, genetic improvement by crossing among these groups can exploit heterotic hybrids.
