Breeding and Cultivation Techniques of a New Jute Variety Minghuang No.1

优质高产抗病圆果黄麻新品种‘闽黄1号’是以圆果种黄麻‘孟引1号’为材料,采用Co60 2.5万伦琴γ射线辐射诱变,以选择高产、稳产、优质、抗病为目标,经7年9代系谱选择育成。2011-2012年参加全国黄麻新品种区域试验,平均纤维产量3 131.25kg·hm-2,比对照‘黄麻179’(CK1)增产7.45%,比对照‘宽叶长果’(CK2)增产8.08%,均达极显著水平;2012年参加全国黄麻新品种生产试验,平均纤维产量2 964.75kg·hm-2,比对照‘宽叶长果’(CK2)增产7.36%,且纤维品质优良,是一个优质高产抗病的黄麻新品种。

With the goal for breeding high and stable yield ,superior quality and disease resistance jute varieties ,a new superior quality ,high yield and disease resistance jute variety-Minghuang No.1 was bred through 9 generations in 7 years derived from Mengyin No.1 irradiated with Co 60-γ rays （25000R） .In a national regional trial for new jute varieties in 2011-2012 ,the yield of new variety′s average fiber was 3 131.25 kg · hm -2 ,7.45% and 8.08%more than that of Huangma 179 （CK1 ） and Kuanyechangguo （CK2 ） .The difference was extremely significant at the level of 0.01. In a national production test for new jute varieties in 2012 ,its average yield of fiber was 2 964.75 kg · hm -2 ,more 7.36% than that of Kuanyechangguo （CK2 ） .The difference was ,also extremely significant .The fiber quality of the new variety was superior to the control .So it was a new superior quality ,high yield and disease resistance jute variety .
