在车排子试验站枯萎病菌车排子菌系生理小种 7号病圃对引进的 2 8个棉花品种进行抗病性测定 ,结果表明抗棉花枯萎病生理小种 7号的高抗品种为豫早 95 40 8;抗病品种 10个为低酚 34、豫早 5 16、锦棉 812、中 12、辽 12、鲁 H2 8、鲁 H12 3、中 19、衡 8930、邯无 2 3;耐病品种 5个为豫早 95 439、8815 46、880 1、鲁 OH6、中 2 3;感病品种 12个为 841、甘棉 4号、辽 2 0 48、中 9 61793、锦棉 5号、130 4、锦 92 90 4、82 2、鲁 OH15、鲁 2 H3、880 32 7、鲁 742。综合分析结果表明 ,在 1997年特殊的生态气候条件下 ,中晚熟品种霜前花率达 90 %以上 ,甚至 10 0 %。邯无2 3、豫早 5 16、中 2 3、中 12、中 19、锦 92 5 0 4、鲁 H12 3、鲁 OH6、低酚 34、衡 8930、锦棉 5号 11个晚熟品种皮棉单产均在 30 0 0 kg/hm2以上。其中豫早 5 16具有高产、优质、抗病及高衣分等特点 ,前期发育快 ,生长势强 ,中期结铃率高 ,后期含絮力强 ,生育期比新陆早 1号偏晚 12天 ,比新陆早 4号、5号分别偏晚 4天和 11天。
In the car row test station Fusarium oxysporum subsp. Paratyphoid race 7 on the introduction of 28 cotton varieties tested for disease resistance, the results showed that resistance to cotton blight physiological races on the 7th high-resistant varieties Yu early 95 40 8; resistant varieties of 10 low-34, Henan early 5 16, Jinmian 812, in 12, Liao 12, Lu H2 8, Lu H12 3, in 19, balance 8930, Five resistant varieties were early Yu 95 439, 8815 46, 880 1, Lu OH 6, Zhong 2 3; the susceptible varieties 12 were 841, Gannan 4, Liao 2048, Zhong 9 61793, Jinmian 5, 130 4, Jin 92 90 4, 82 2, Lu OH15, Lu 2 H3, 880 32 7, Lu 742. The comprehensive analysis shows that under the special ecological climatic conditions in 1997, the rate of flowering of middle and late-maturing varieties reached more than 90% or even 10% before frost. Handan no 2 3, Henan early 5 16, in 2 3, 12, 19, Jin 92 5 0 4, Lu H12 3, Lu OH6, low phenol 34, Heng 8930, Jinmian 5 11 late varieties of lint yield All above 30 0 kg / hm2. Among them, Yu-516 had the characteristics of high-yield, high-quality, disease-resistant and high-coat differentiation. The early development was rapid, the growth vigor was strong, the mid-term high bolus rate was high, Day, four days earlier than Xinlun and four days late on the 5th.
