Capsicum (Solanaceae), comprising of sweet and hot chilli pepper, is a globally known spice crop. This genus is well known for its huge genetic diversity at intra- and inter-species level. Diversity among Akabarechilli landraces, a unique Capsicum from Nepal, has not been studied so far. The present study characterized thirty accessions of Akabarechilli using 26 qualitative and 21 quantitative agro-morphological markers at the experimental plots of National Genebank, Khumaltar, Nepal during the summer season of 2018/019. Using principal component analysis, the first- principal components with eigen-values more than 1 contributed 25% of the variability among accessions for quantitative traits, whereas the first principal components with eigen-values more than 1 contributed 22.2% of the variability among accessions for qualitative traits. These findings suggested a wide range of morphological variations among the tested accessions. Based on qualitative and quantitative traits, 30 accessions were grouped into 6 distinct clusters by Euclidian distance and average method. Accessions CO-11048 and CO-11050 under cluster-III were round shape fruit type and accessions CO-11044, CO- 11046 andCO-11047 under cluster-I were high fruiting with longer fruitbearing period and could be utilized for breeding purpose as these are the traits preferred by consumers or processors in Nepalese market.

Spot blotch (Bipolaris sorokiniana) is a major disease of wheat in warm, humid wheat-growing regions. The aim of present study was to evaluate the infection symptomology and disease severity to different wheat varieties under laboratory condition. A total of ten wheat genotypes including RR-21 (a susceptible check) and Aditya (a resistant check), were evaluated for seedling stage resistance to spot blotch disease through artificial inoculation under laboratory condition at Gokuleswor, Baitadi during 2018. Based on disease severity and area under disease progress curve (AUDPC), Aditya was found resistant and RR-21 was found susceptible The tested genotypes were categorized on the basis of total AUDPC value, where Banganga, BL4341, BL4407 and local genotype were moderately resistant, BL-4406, NL-1190, NL-297 and NL-971 were found moderately susceptible to spot blot at seedling stage. The susceptible check, RR-21 had the highest disease severity (44%) as well as mean AUDPC value (51.38).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
