为了适应上海郊区粮食三熟制的需要,我所采用杂交、辐射育种等方法,结合异地繁育,加速世代,初步培育出若干大、元麦新品系,经过品种比较和郊县试种,表现早熟、高产,现分别介绍如下: 大麦新品系“76—23”“76—23”是我所在1968年用“浙杂 12”与“早熟3号”配制的杂交组合所育成的二棱大麦新品系。在院内1976、1977两年的品比试验中,“76—23”大麦分别比“早熟3号”增产9.8%、17.2%。去年大区生产试验(面积
In order to meet the needs of the three suburban grain system in Shanghai, I used hybridization, radiation breeding and other methods, combined with off-site breeding, accelerating generation, initially nurtured a number of new varieties of wheat, after comparison of varieties and suburbs of the trial, the performance of precocious , High yield, are introduced respectively as follows: New lines of barley “76-23” “76-23” is my new line of barley obtained in 1968 with “Zheza12” and “precocious 3” . In the trial of two years in 1976 and 1977, barley yield of “76-23” increased by 9.8% and 17.2% respectively compared with that of “precocious 3”. Last year, large-scale production test (area
