河南7602是适于油菜茬的棉花早熟品种。由河南省农科院经济作物所育成.其父本为辽棉3号选系,母本为乌干达4号。该品种连续四年参加省棉花早熟品种多点试验鉴定,1977~1979年平均亩产皮棉142.3斤,比对照黑山棉增产30.7%,比徐州142增产16.9%;1980年平均亩产166.3斤,比对照黑山棉增产40%,比鲁棉1号减产1.4%,但10月20日前收花量却比鲁棉1号高62%,早熟性显著。河南7602生育期110%120天,株型紧凑,株高中等,茎色紫红,茎秆坚韧不易倒伏,叶片较小,有茸毛,叶色浅,棉铃中等稍长,单铃重5.5克,铃壳较厚,吐絮畅,不易落絮。早熟不早衰。绒长30毫米以上,衣分35~37%。在中等肥力条件下,每亩产量不低于百斤。现已在河南省两熟棉区和盐 Henan 7602 is suitable for early crop varieties of rape stubble. It is bred by the Economic Crops Institute of Henan Academy of Agricultural Sciences and its male parent is Liaoning Cotton No.3, the female parent is Uganda No.4. The varieties of cotton varieties to participate in the province for four consecutive years of multi-point trial identification, 1977-1979 average yield of lint 142.3 kg, compared with the control Montenegro cotton yield 30.7%, yield 16.9% higher than in Xuzhou 142; average yield of 166.3 kg in 1980, the ratio Control Montenegro cotton yield increased 40%, 1.4% reduction than the Lilian 1, but the October 20 harvest compared with the Lumi cotton 1 62%, precocious significant. Henan 7602 Growth period 110% 120 days, plant compact, medium plant height, stem purple color, stalk tough and easy to lodging, leaves smaller, hairy, leaf color shallow, slightly longer cotton bolls, boll weight 5.5 grams, bell Thick shell, spit floc smooth, not easy to fall off. Premature aging is not premature. Long cashmere 30 mm above, clothing points 35 to 37%. Under medium fertility conditions, the yield per mu is not less than 100 jin. Two cotton fields are now in Henan Province and salt
