Ⅱ32A是湖南杂交水稻中心培育成功的新不育系,该不育系穗大粒多、柱头外露好、异交结实率高、制种繁殖易获高产,与现出恢复系配组的杂交一代比汕A、威A等不育系配制的组合优势强。据全国南方稻区区试结果,由Ⅱ32A×测64—7配制的Ⅱ优64组合,连续三年均居晚稻杂交早熟新组合首位。为了尽快推广应用这一科技新成
Ⅱ32A is a new male sterile line cultivated successfully in hybrid rice center in Hunan Province. The male sterile lines are more spikelets, more exposed stigma, higher seed-setting rate, higher yield and breeding, Shantou A, Granville A and other sterile lines prepared combination of strong advantages. According to the results of the rice test in southern China, the combination of Ⅱ You 64, which was prepared from Ⅱ32A × 64-7, ranked first in the new combination of early maturity of late rice for three years in a row. In order to promote the application of this new technology as soon as possible
