Abstract

Forty nine apricot (Prunus armeniaca L.) genotypes collected from NBPGR, New Delhi, and North West Himalayan region of India and studied to assess the overall degree of polymorphism, detect similarities among important pomological, fruit quality and yield parameters. Genotypes differed significantly for above traits. Thirteen variables were scored and subjected to multivariate analysis. Results showed a considerable phenotypic diversity among apricot genotypes. The cluster analysis classified genotypes into two major groups according to their potential
characteristics. The first group was found superior in terms of fruit and yield related characteristics and second group in fruit quality attributes. Principal component analysis (PCA) revealed that the first PC, which is the most important component, explained 46.68 % of total variation and was positively related to number of fruits/plant, fruit length, fruit diameter, fruit weight, stone length, stone diameter, stone weight, kernel weight, kernel diameter, kernel length and yield/plant and negatively related to acidity and genotypes in CITH-AP 1, CITH-AP 2, CITH-AP 3, Erani, CITH-AP 36, Afglani and Harcot were found unique for fruit and yield attributing traits.
