杂交水稻的育成与推广,对我省的粮食生产起了显著性的增产作用.但是,目前大面积推广应用的杂交水稻组合,普遍存在着生育期长(大部分地区不宜于早季种植),抗性衰退,病害严重等的缺陷.为此,培育生育期短、抗逆性强、丰产性好、适应性广的杂交水稻新组合,成为育种单位的燃眉之急.我们针对现有杂交水稻组合的缺陷,在育种中以早、丰、抗为中心,经过多次的反复试验、鉴定,于一九七八年培育出威优33杂交水稻.通过多点、多
The development and popularization of hybrid rice played a significant role in increasing grain yield in our province.However, the current hybrid rice combination popularized in large areas has a long growing period (most areas should not be planted in early growing season) Therefore, it is urgent to breed a new hybrid rice combination with short growth period, strong resistance, high yield, good adaptability and wide adaptability.Aiming at the problems of existing hybrid rice combinations Defects, breeding early, abundance, resistance as the center, after repeated trial and identification, in breed Weiyou 33 hybrid rice in 1978.
