高产、早熟、抗病油菜新品种川油11的选育与推广

BREEDING AND POPULARRIZING OF NEW HIGH YIELD EARLY MATURITY AND DISEASE RESISTANCE CULTIVAR CHUANYOU 11

油菜新品种川油11,在多年多点试验和大面积推广中,表现出产量高、早熟、适应性强,因而得到大面积推广,取得了较好的社会和经济效益.选育甘蓝型早熟品种,产量突破的技术关键,是调整株型和果粒结构中,即以增加主花序长和提高单果粒重为重点,以提高品种的综合抗性为基础.川油11就是根据这一技术路线育成的.

A new rape cultivar Chuanyou Ⅱ shows characters of high yield,early maturity and wide adaptation during the period of its multilocation experiments and in large area popularization for years.It has been cultivated in large scale,and better social and economic benefits have been achieved.The key tech- niques to increase the yield in a great scale for developing early maturing cultivar are to rearrange the plant structure and the pod-grain component,i.e.to increase the length of major inflorescence and the grain weight per pod on the basis of improving the integrative resistance.Chuanyou Ⅱ was developed upon this technical line.
