为了及早找出高产、抗逆性强的小麦新品种,1975年我们从中国农林科学院引进了四个品种,以当地推广良种农大139为对照进行试种比较,发现九三红(见封面图3)表现最好(本刊于1976年第8期曾对九三红品种作过介绍——编者)。在1976年0.13亩面积试种的基础上,1977年试种60亩,1978年扩大到300亩。通过三年的连续试种,九三红表现早熟(与农大139相比,出苗早1—2天,成熟早4—5天)。抗病(三年试种中,除今年发现有少量白粉病外,无其它病害)、抗寒(在1977年持续低温、大面积受冻
In order to find out the new wheat varieties with high yield and strong resistance as early as possible, we introduced four varieties from the Chinese Academy of Agriculture and Forestry in 1975 and compared them with the local popularization program “Nongda 139” ) Best performance (this issue in 1976 No. 8 had introduced ninety-three red varieties - editor). On the basis of 0.13 mu area trial in 1976, 60 mu was planted in 1977 and expanded to 300 mu in 1978. Through three consecutive years of trial planting, 93% of red showed early maturity (compared with 139 of Nongda, 1-2 days early emergence, mature 4-5 days earlier). Disease resistance (three years of trial, except this year found a small amount of powdery mildew, no other diseases), cold (continued low temperature in 1977, a large area of frozen
