“…These traits are correlated and the genotypes were linked with the traits. According to the biplot analysis conducted by Akand et al (2016), the optimal genotype is located near the arrowhead. According to their findings, G25 is located in cluster V and positively favored the traits fruit weight (g), fruit length (cm), and yield per plant (g).…”

Pepper (Capsicum spp.) is a major spice crop around the globe. The major goal of the experiment was to evaluate the genetic diversity amongst 30 pepper germplasms for twelve morphological and phytochemical parameters. The investigation was conducted between November 2019 and April 2020 using a randomized complete block design with three replications in the experimental field of Hajee Mohammad Danesh Science and Technology University, Dinajpur, Bangladesh. The results revealed a notable disparity across the genotypes for all studied traits. The genotype C80 displayed the highest fresh fruit weight (20.60 g) and dry fruit weight (1.20 g). Once again, the genotype YF1 had the highest chlorophyll and vitamin-C contents. The most significant correlations were revealed between fresh fruit weight and dry fruit weight (r = 0.83***) followed by between fruit diameter and dry fruit weight (r = 0.80***), and between fruit diameter and fresh fruit weight (r = 0.79***). The Wards-D method was used to cluster thirty genotypes into four clusters based on Euclidean distances. Cluster IV consisted of a maximum of 13 pepper genotypes. Cluster I yielded the greatest fresh fruit weight, measuring 11.75 g, whereas cluster III contained the highest Vitamin-C content, measuring 23.61 mg/ 100 g. The clusters I and III had the highest inter-cluster distances (6.45), while cluster I had the highest intra-cluster distance (2.36). PC1 and PC2 explained 32.8% and 18.3% of the total variances, respectively. In the biplot, the genotypes C54 and C80 favored fresh and dry fruit weights as well as fruit diameters, while the genotypes C29 and YF1 positively favored chlorophyll and vitamin-C contents. Therefore, the diverse pepper genotypes C54, C80 from cluster I and C29 and YF1 from cluster III could be included in future hybridization of pepper breeding.

The study was designed to validate the previously reported 34 SSR markers using 78 chilli genotypes to detect significant trait specific markers as well as superior genotypes resistant to Phytophthora capsici root rot (PcRR). In this context, the identification of germplasm with higher yield per plant (YPP) leads to hype in stress tolerance index (STI) in genotypes, Chakwal3 (11.98), Greenfire (10.14), Advanta5017 (9.94) and Chakwal4 (7.8). The identified genotypes were also found as resistant and moderately resistant due to existence of below 50% of disease incidence. Moreover, biplot showed the interrelation of STI with YPP through the formation of acute angle by their respective vectors. In the current study, the markers Hpms1172 and CAMS177 was found significant for STI. However, the marker CAMS066 was found associated with relative cell injury, CA06g27450 with disease incidence and CAMS173 with relative leaf damage. The bright bands on gel pictures of significant markers showed the association of these markers with resistant genotypes i.e. Chakwal3, Advanta-5017 and Chakwal4 as well as with a single moderately resistant genotype i.e. Greenfire. The markerstudes confirmed the phenotypic data by showing association of markers i.e. Hpms1172 and CAMS177, r with stress tolerance index. The principal coordinate analysis aligned with the results obtained from marker-assisted selection. Thus, currently practiced marker assisted selection detected high yielding genotypes in PcRR disease stress condition that will be helpful in progressing breeding programs in chilli.
