云研1号有性系是GT1与PR107双无性系种子园的杂交后代,经多年试验鉴定,于1980年正式向以辐射降温为主的二、三类型区作为推广生产的种植材料。 1.主要经济性状: 经多年的抗性,产量等方面的鉴定证实是一个对辐射低温为主的寒害抗性较强的有性系,它产量中等,比较速生,并无其它不良付性状。 Yunyan No.1 sexual line is the hybrid progeny of GT1 and PR107 double clonal seed orchard. After several years of experiments, it was formally known as the second and third type of zone that radiate the temperature drop in 1980 as the planting material for popularization and production. 1. The main economic traits: After many years of resistance, yield and other aspects of the identification proved to be a low temperature-based radiation cold-resistant sex sexual line stronger, its yield is moderate, relatively fast-growing, no other adverse pay-like traits.
