自70年代中到80年代初,大面积推广了高抗棉枯萎病的陕401和陕1155棉花品种,其丰产性很好,但晚熟。1981年秋季遇低温阴雨,晚熟损失惨重,全省亩产皮棉仅14.95kg,棉农强烈要求选用早熟品种,才引起各方面重视。然而,我省与陕401和陕10155先后选育和参加试验的抗病中早熟品种有陕棉4号,陕5245、成棉153等,吐絮畅而集中、霜前花高。在当时都未很好推广利用。其中5245抗病性好,中早熟,
Since the mid-1970s to the early 1980s, Shaanxi 401 and Shaanxi 1155 cotton varieties with high resistance to Fusarium wilt were popularized on a large scale. Their high yield is good but late-maturing. In the autumn of 1981, when it suffered from low temperature and rainy weather, the late-ripening suffered heavy losses. Only 14.95kg of lint per mu was produced in the province. The cotton farmers strongly demanded the selection of precocious varieties, which aroused the attention of all parties. However, Shaanxi Province and Shaanxi 401 and Shaanxi 10155 successively breeding and participating in the test of early maturing varieties are Shaanxi cotton 4, Shaanxi 5245, cotton 153, etc., spit floc smooth and concentrated, before frost flower. At that time did not promote the use of good. Which 5245 good disease resistance, early maturity,
