Characterization and Diversity Assessment of Nepalese Garlic (Allium sativum L.) Landraces

A research was carried out at the field of National Agriculture Genetic Resources Centre (NAGRC), Khumaltar, Lalitpur, Nepal in 2019 with objective phenotypic characterization and genetic diversity assessment thirty-seven local garlic landraces. The assessed based on fifteen qualitative nine quantitative characters by sing non replicated rod row design following descriptors developed IPGRI, 2001. Descriptive statistics were calculated using MS Excel 2016 UPGMA clustering PCA done MINITAB-17. index (H’) coefficient variation for different traits ranged from 0.54-0.96 16.89-87.85, respectively. Four clusters identified CO 10307, 10482 10615 fourth superior terms characters. Five principal components contributed95.2% cumulative variance. This result will be helpful breeder researchers to comprehensively understand agro-morphological as well Nepalese collection.
