围绕改良早籼稻品质、增强其稻瘟病抗性的目标,利用已有的优质稻中间材料进行有性杂交,采取本地选育与病圃筛选同步进行的办法,结合南宁、海南南繁加代,较好地将“优质、高产、早熟、抗病”结合在一起,育成抗稻瘟病优质稻中熟早籼新品种湘早143。对其特征特性及在南方稻区区试的表现作了介绍。
Focusing on the goal of improving the quality of early indica rice and enhancing the resistance of rice blast, the existing high quality rice intermediate material was used for sexual hybridization. The methods of local breeding and screening were combined simultaneously, Good “high quality, high yield, precocity, disease resistance,” combine together to develop high-quality rice blast resistant mid-early indica hybrid rice Xiang early 143. Introduced its characteristic characteristic and the performance in the southern rice area test.
