搞好棉花良种繁育,保持品种种性的稳定,可以延长新品种的使用年限,充分发挥其社会经济效益。我场培育的高产棉花品种泗棉2号,1984年通过审定后即在长江中下游棉区推广种植,1988年和1989年又分别通过湖南省及国家级品种审定。1990年种植面积还继续扩大,湖南省1990年由上年的十几万亩迅速发展到70多万亩。该品种之所以推广面积大,使用时间长,除了它有良好的丰产性能以外,主要得益于科学的良种繁育技
Do a good job breeding cotton seed varieties to maintain the variety stability, you can extend the useful life of new varieties, give full play to their social and economic benefits. In our field, the high-yielding cotton variety Simian 2 was promoted for planting in the middle and lower reaches of the Yangtze River after it was validated in 1984. In 1988 and 1989, it was approved respectively by Hunan Province and national level. The area planted in 1990 also continued to expand. In 1990, Hunan Province developed rapidly from more than 100,000 mu in the previous year to more than 700,000 mu. The reason why the variety of large-scale promotion of the product, the use of a long time, in addition to its good yield performance, mainly due to scientific breeding technology
