为加快育种进程,我们从1980年开始,结合杂交育种,利用温室和当地早春的自然低温条件,进行了冬小麦新品种就地加代选育的研究,经过连续五年的试验,已取得一年两代的繁育效果,并选出了部分有希望的品系。如三年出圃的83—21,1985年参加临沂地区中肥组区域试验,七处试点平均比省定对照种山农辐63增产16.86％,并通过本省中肥区试的预备试验,提升参加了1985～1986年度的省中肥区域试验。选出的旱地品系83—26(三年出圃),经本所两年试验,比全国统一旱地对照种北京10号,分别增产
In order to speed up the breeding process, we started with the study of in situ hybridization and selection of new winter wheat varieties by combining crossbreeding with natural low-temperature conditions in the greenhouse and local spring in 1980. After five consecutive years of trials, Generation of breeding effect, and selected some of the promising strains. For example, three years from the nursery 83 - 21, in 1985 to participate in Linyi regional fertilizer group test, seven pilot average than the provincial control of the mountain agricultural spokes 63 yield 16.86%, and through the province of fertilizer test trial to enhance participation From 1985 to 1986, the regional fertilizer experiment in the province. The selected dry land system 83-26 (three years out of nursery), two years of the trial by the Institute, than the national standard for a unified Beijing dry land comparison, respectively, increased production
