抗病高产转基因抗虫棉豫068的选育

转基因抗虫棉豫068是河南省农业科学院经济作物研究所以R613为母本、中棉所41优良品系为父本,通过杂交系谱法选育而成的。2009-2010年在河南省棉花品种区域试验中,皮棉平均产量1 506.0kg/hm2,比对照鲁棉研28增产7.3%。2011年在河南省棉花品种生产试验中,皮棉平均产量1 297.7kg/hm2,比对照鲁棉研28增产5.8%。枯萎病和黄萎病病情指数分别为4.6和28.0,对棉铃虫抗性达到2级水平。该品种于2012年通过河南省品种审定委员会审定,适宜在黄河流域种植。

Breeding of Transgenic Insect Resistant Cotton Yu 068 with Disease Resistance and High Yield

Yu 068 was a transgenic insect resistant cotton variety developed by Industrial Crops Institute of Henan Academy of Agricultural Sciences,which was bred by crossing R613 with the fine strain of Zhongmiansuo41.The average lint cotton yield of Yu 068 was 1 506.0 kg/ha in cotton variety regional trail in Henan province in 2009-2011,7.3% higher than CK,and 1 297.7 kg/ha in cotton variety production test in Henan province in 2011,5.8% higher than CK.The disease indexes of Fusarium and Verticillium wilt of Yu 068 were 4.6 and 28.0,respectively,and its cotton bollwarm resistance reached to the level of 2.This variety was approved by Henan Variety Evaluation Committee in 2012,and it was suited for cultivation in the Yellow River valley.
