“甘油5号”(原754)是我所用钴~(60)伽玛射线14万伦琴处理胜利油菜,从其后代中经单株—集团—混合选择等方法,于1970—1977年选育成的。一、产量表现:甘油5号于1972—1973年参加选种圃进行株系鉴定,根据当年测产结果,折合亩产232.9斤,较早中熟对照品种“甘油1号”增产38.88%,1973—1974年参加鉴定圃产量试验,折合亩产352.9斤,比甘油1号增产24.96%,两年平均较甘油1号增产31.42%。1974—1977年甘油5号连续三年参加我所品种比较试验,在前两年试验中,分别较中熟对照品种甘油3号增产27.08%和10.17%。1976—1977年是历史上罕见的冬季干冻年份,加之开花后长期阴雨低温,对油菜大面积生产
“Glycerol 5” (formerly 754) was the result of a single-group-hybrid selection from its offspring of 147,000 Roentgen of Cobalt ~ (60) gamma irradiation that I used for breeding in 1970-1977 . First, the yield performance: Glycerol in 1972-1973 to participate in the selection of nurseries for identification, according to the test results of the year, equivalent to 232.9 kg per mu, the earlier maturing reference variety “glycerol 1” increased yield 38.88%, 1973 In 1974, it took part in the yield test of identification garden, equivalent to 352.9 kg per mu, an increase of 24.96% over that of glycerol 1, an increase of 31.42% over the average of two years. In 1974-1977, glycerol 5 participated in the comparative trial of our species for three consecutive years. In the first two years of experiment, it increased by 27.08% and 10.17% respectively compared with that of medium-maturing reference glycerol No.3. 1976-1977 is the history of rare winter dry years, combined with prolonged overcast rainy after flowering, large-scale production of rape
