新疆核桃栽培历史悠久,种质资源丰富,但因长期实生繁殖和异株授粉,形成了良莠不齐的混合群体,普遍结果迟、产量低、品质差,没有定型的品种.我们从1976年起,以选为主,选、育、繁相结合,选出一批优树,通过无性繁殖,对其无性系(高接树和幼龄树)进行测定和生产试验,将典型性状一致、遗传性相对稳定及增产显著的无性系加以推广.1985年自治区林业厅主持召开核桃成果鉴定会通过并定名为新丰、新光、新露的三个核桃优良品种,均具有早实、丰产、优质的特性,现将它们的选育经过介绍如下. Xinjiang walnut cultivation has a long history, rich germplasm resources, but due to long-term real-life breeding and heterosis pollination, the formation of a mixed group, the general results of late, low yield, poor quality, no stereotypes of the variety. We from 1976 onwards Selected as the main election, education, complex combination of a number of excellent trees selected by asexual reproduction, its clones (tall and young trees) test and production tests, the typical traits, genetic relative Stability and yield significant clones to be promoted .1985 Autonomous Region Forestry Department presided over the walnut fruit identification will be passed and named the Xinfeng, Shin Kong, Xinlu three varieties of walnut, are of early real, high yield, high quality characteristics, Now their breeding after the introduction are as follows.
