Abstract
Peach belongs to family "Rosaceae" an important fruit crop of temperate regions. Worldwide, peach cultivation is gaining interest due to its nutritional values. In Pakistan, various local and exotic genotypes exits that are hardly studied and are not adequately characterized. Therefore, there is a need to characterize these genotypes as they are helpful in developing new varieties that may be better adapted to climate change. In this study, we shall collect 10 peach genotypes from different Punjab & Khyber Pakhtunkhwa districts and will characterize them on the basis of morphological traits. For morphological characterization, the IPGRI descriptor was followed. Thirty three qualitative traits were studied for the estimation of peach diversity. Among these morphological traits, highest coefficient of variation was observed in anthocyanin coloration of flesh abbreviated as ACOF (81.65 %). While others higher CV were observed in parameters like fruit over color; (FOC), flesh fibers; (FF) and flesh type; (FT), (80.39 %, 65.75 %, and 63.05%) and the least CV was observed in anthocyanin coloration of flesh around stone; ACFAS, (23.44 %), followed by stone shape; SS, (25.448 %). For morphological quantitative traits maximum CV was observed in fruit weight (23.841 %). While others higher CV were observed in parameters like stone weight, stone width (23.634 % and 22.057 %) and the least CV was observed in Fruit Width (5.582 %).
