摘要
科阳5号(原代码T95)是通过细胞核质互作雄性不育杂种优势利用途径,采用测交、回交、自交等方法育成的三系食用向日葵杂交种。该杂交种丰产、抗病、商品性好,在内蒙古区域试验中,平均产量3406.5kg/hm2,比对照DK119增产13.2%,比对照SH909增产9.30%。
In the method of nucleo-cytoplasmic interraetion male sterility heterosis,Keyang No.5 （old code： T95）,a new triple crossing hybridization of confection sunflower,was bred by the way of test cross,back cross and self cross.This cultivar possessed of fertility,disease resistance and good commodity characters. In Regional Test of Inner Mongolia,the yield of Keyang No.5 was 3406.5kg/hm2.which out-yielded the control DK119 by 13.24% and SH909 by 9.30%.
