夏播油葵新品种运葵4号的选育及配套技术

运葵4号是山西省农科院棉花研究所选育的油用向日葵三系杂交种,适宜各产区春播和冬麦茬夏播,具有产量高、含油率高、结实率高、抗逆性好等特点。2000～2002年参加山西省向日葵生产区域试验,3年平均单产2643kg/hm2,比美国G101增产7.4%。经农业部油料及制品质量监督检验测试中心对2002年复播运葵4号测定,子实含油率为42.33%。2003年3月通过山西省农作物品种审定委员会审定。提出运葵4号的高产栽培技术措施和大面积制种配套技术。

The Study of Breeding and Associated Technic of a New Variety of Oil-Sunflower YUNKUI 4

Three-line hybrid YUNKUI 4 of oil-sunflower, has been bred by Cotton Research Institute, Shanxi Academy of Agricultural Sciences, which is suitable to plant in spring or summer after wheat harvest in all regions, and possess the trait of higher yield,oiliness rate,seed rate and stress resistantant. After three years (2000～2002) breeding test in different regions of Shanxi province, the average yield of YUNKUI 4 was 2 643kg/hm2, 7.4% higher than U.S. G101. Mensurated the seed of YUNKUI 4 planted in 2002 by the Intendance and Detection Center of Agriculture Department of oil plant and their produce quality, the oiliness rate of the seed was 42.33%, the contrast G101 was 42.23%. In Mar 2003, YUNKUI 4 passed the evaluation by Committee of Crops Evaluation of Shanxi province. In this article we also recommented the technology system of high yield and seed hybridization in a large scale.
