遵照毛主席关于“有了优良品种,即不增加劳动力、肥料,也可获得较多的收成”的教导,我场从1964年开始,在提纯复壮棉花原有品种的同时,开展了棉花新品种系统选育工作。至1968年,从锦棉一号中系统选育出优良品系68—3,1974年定名“黑山棉一号”,列为省内推广的棉花新品种。 Following Chairman Mao’s teachings on “excellent varieties, that is, we can get more crops without increasing labor force and fertilizer,” our field started from 1964 to purify and rejuvenate the original varieties of cotton while carrying out the cultivation of new cotton varieties System selection work. By 1968, a fine line of 68-3 was bred from Jinmian No.1 System, and named “Heoshan Cotton One” in 1974 as a new cotton variety promoted in the province.
