矛羽早是我所于1974年从秋播白菜型油菜矛羽品种(由甘肃省永登县良种场引进)中系选培育而成。1976年在旅大地区16个点进行试验,其中有14个点增产:比门源油菜增产10%的有3个点;4个点增产15%;5个点增产20%;2个点增产30%以上,1个点减产3.7%。1976年在北方10省(市)油菜区域试验中,在旅大地区矛羽早比门源油菜增产27.5%,产量居第二位;1977年它比门源油菜增产59.8%,产量居第一位。
Spear plume as early as I was in 1974 from the autumn sowing cabbage rape spear varieties (from Gansu Province Yongdeng County introduction of good seed field) selected from the Department of breeding. In 1976, 16 trials were conducted in the Luda District, of which 14 points increased production: 3 points more than 10% of the original canola; 15 points increased from 4 points; 20 points increased from 5 points; and 2 points increased production More than 30%, 1 point reduction of 3.7%. In the experiment of rapeseed in 10 provinces (cities) in the north of China in 1976, the spear plume increased by 27.5% and the output was the second highest in the Luda area in early 1976. The yield increased by 59.8% and the output was the highest in 1977 Bit.
