Genetic Bio-diversity in the Segregating Population of Walnut (Juglans regia L). At Kurram Agency, Parachinar

Abstract

Four varieties for instance, Kurram-1, Kurram-2, Kurram-3 and Kurram-4 were screened out from the segregating population at Kurram Agency, Parachinar. Maximum Stem diameter, wider plant spread, significantly higher yield were observed in Kurram-2. Early nut maturity, average Kernel weight, average Kernel percent, lesser number of nuts/Kg and very thin shelled were noted in Kurram-1. Kurram-3 had late matured, more nuts/Kg, thin shelled and more oil percent. Maximum nuts/Kg, very thin shelled and maximum oil percentage were dominanted in Kurram-4. Scion/bud wood of these walnut varieties are available on request to the Director,

Screening and Evaluation of Exotic and Indigenous Walnut Genotype and Varieties

“…Individual walnut trees are grown along boundaries of fields, channels, and backyards, etc. Mostly Pakistan seedlings are commercially grown, however some exotic cultivars have also been tried from time to time at research stations such as `Chandler', 'Hartley', 'Lam', `Germisara', lupanesti', `Valerie,'Odum', 'Sere and `Sulemani' [16] and many local selections like `MS-1′, `MS-2′, 'MS-18′ from Malakand, `SW-1′, `SW-3′ from Swat, `Dir-2′ and 'Chitral-I', `Chitral-2′, `Chitral-3′, (, `Kurram-1′,'Kurram-2′, 'Kurram-3′, 'Kurram-4′ [17].…”
