转双价抗病基因(Chi+Glu)棉和多种不同性状棉抗黄萎病性比较

Comparison of Resistance to Verticillium wilt between Transgenic Cotton with Double Disease-resistant Genes(Chi+Glu) and Other Cotton Varieties with Different Traits

试验比较了转双价抗病基因(Chi+Glu)棉与多种不同性状棉花的抗黄萎病性,结果表明:参试7个材料,转双价抗病基因(Chi+Glu)棉抗病性排名第一,病指4.47(高抗病);中棉所24其次,病指4.68(高抗病);209复合性状转基因(Chi+Glu+Bt+EPSPS)杂交棉F1病指8.55(抗病),排名第三;赣棉杂109抗虫棉病指10.66(抗病),排名第四;其余材料为感病。

The resistances of transgenic cotton with double disease-resistant genes（Chi＋Glu） and other cotton varieties with different traits to Verticillium wilt were compared through field test.The results showed that： among 7 tested cotton varieties,the transgenic cotton with double disease-resistant genes（Chi＋Glu） had the strongest disease resistance,and its disease index was 4.47（high resistance）;followed by Zhongmiansuo 24,its disease index was 4.68（high resistance）.The transgenic hybrid cotton F1 with 209 complex character genes（Chi＋Glu＋Bt＋EPSPS） had the third strongest disease resistance,with the disease index of 8.55（disease-resistant）.The disease index of transgenic insect-resistant cotton variety Ganmianza 109 was 10.66（disease-resistant）.The other tested varieties were susceptible.
