Genetic variation among biofortified and late blight tolerant potato (Solanum tuberosum L.) (mini tuber) production in Bangladesh

Biofortified potato could contribute a major role in food security for millions of people. It help to alleviate worldwide micronutrient malnutrition. An experiment was carried out during 2019-2020 growing season with 49 accessions following randomized complete block design three replications order evaluate and classify agro-morphological traits Breeder seed production centre (BSPC), Debiganj, Panchagarh. Eight quantitative characters i.e. germination percent, foliage coverage, stem number per hill, plant height, vigor, tuber plant, weight yield were measured. Principal components (PC) analysis showed explained 72.16 % the total variation among traits. The first PC assigned 35.22 second 58.47 between more related tuber. Forty-nine germplasm placed on cluster based using hierarchical classification (HCA). All discriminated high morphological observed. Thus, outcomes principal component used study have revealed level genetic contributing identified. CIP403, CIP404, CIP405, CIP413 CIP445 identified as superior relationship PCA bi-plot.
