杂交高梁在全国虽已得到普遍推广,并发挥了很大增产作用。但杂交高梁一般都有一个很大缺点,难捉苗,播浅了难保墒,播深了不易出苗,常常由于缺苗断垄影响到杂交高粱增产潜力的充分发挥。群众反映:杂交高梁就是好,不易捉苗要研讨。因此,解决杂交高粱捉全苗问题,是当前高粱生产上的一个重要问题。遵照毛主席“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,1972年我们从山西忻县地区引进忻革7号 A 不育系与本地品种娃娃头高粱进行杂交试验,配制出一个新杂交组合——忻革7号 A 不育系×娃娃
Crossbred sorghum has been widely promoted throughout the country and played a significant role in boosting production. However, hybrid sorghum generally has a big disadvantage, hard to catch seedlings, shallow sowing difficult to maintain soil moisture, sowing is not easy to emerge, often due to lack of seedlings off ridge affect hybrid sorghum yield potential to give full play. The masses reflect: hybrid sorghum is good, not easy to catch the seed to be discussed. Therefore, to solve the hybrid sorghum catch the whole seedling problem is an important issue in the current sorghum production. In accordance with Chairman Mao “with excellent varieties, that is, without increasing labor, fertilizer, but also get more harvest ” teaching, in 1972 we Xinxin 7 from Shanxi Xin leather introduced a 7 CMS and local varieties of dolls Head Sorghum hybrid test to prepare a new hybrid combination - Xin leather 7 A sterile line × doll
