1974～1979年我们创造了“棉枯萎抗性定向培育法”。用此法能不经杂交在3—5年内将原丰产、优质、而感病的品种定向改造为丰产、优质、高抗的新品种。在获高抗性后,其丰产、优质特性并未发生劣变,反而有所改进,在重、轻、无病地上都较原品种增产。西农岱16抗、中7抗、徐142抗等即用此法育成的新品种。本文介绍了这些品种的育成经过及其抗性、丰产性和品质。事实已证明本法的原理和方法是正确的。
From 1974 to 1979, we created the “Fusarium wilt resistance directed cultivation method.” With this method, it is possible to transform the original high yield, high quality, and susceptible varieties into new varieties of high yield, high quality and high resistance within 3-5 years without hybridization. After being highly resistant, its high yield and high quality traits have not deteriorated. On the contrary, they have improved and increased their yield on the heavy, light and disease-free land. Xi Nong Dai anti-16, 7 anti-resistance, anti-Xu 142 that use this method into a new breed. This article describes the breeding of these varieties and their resistance, high yield and quality. Facts have proved that the principles and methods of this law are correct.
