Abstract

Background and Objective: The present research aims to evaluate and identify some Iranian landraces of Cucrbita sp. with high diversity to plan breeding programs for the studied cultivars.
Materials and Methods: The experiment was carried out in three repetitions based on RCBD in Oshnavieh City, Western Azerbaijan province, Iran. Some important qualitative and quantitative traits of the collected cucurbit genotypes based on the relevant descriptor include Growth habit, branch presence, fruit shape, fruit surface spot, Peduncle length, ripe fruit, seed length, and width, seed shape, 1000 seed weight and kernel to shell ratio were measured and recorded.
Results: Based on the results, the landraces showed a high difference in yield and yield components of fruit and seed. In this study, the highest fruit weight, fruit yield per plant, number of seeds per fruit, and seed yield were obtained in the Qarahziyaaddin landraces. In contrast, the highest seed length was obtained in the Hamadani landraces, and the highest fruit width and thousand seed weight were obtained in the Bal Qabaghi cultivar. The highest flesh-to-shell ratio was related to the Mashhad 10 landrace. In this study, fruit yield significantly correlated with fruit weight and fruit number.
