通过籼粳稻杂交再复交,按照理想株形的要求进行选育,育成了“沈农1033”。经过大面积的试验试种表明,“沈农1033”具有(1)株形好而抗稻瘟病;(2)适于密植而分蘖力强;(3)耐旱力强;(4)温光反应弱,因而适应地区较广;(5)高产而食味又较好等特点。因此“沈农1033”的育成在水稻育种上说明了(1)理想株形育种是水稻高产育种的有效途径;(2)不仅株形好和抗稻瘟性可以结合在一起,高产和食味好也可以结合在一起。
Through crossbreeding between indica and japonica hybrids, breeding was conducted according to the requirements of ideal plant shape and bred “Shennong 1033”. After large-scale test, it shows that “Shennong 1033” has (1) good shape and resistance to rice blast; (2) suitable for close planting and strong tillering ability; (3) The reaction is weak, and thus adapt to a wider area; (5) high yield and taste better. Therefore, the breeding of “Shennong 1033” shows that (1) the ideal plant-type breeding is an effective way for breeding high-yielding rice; (2) Not only the plant shape and the resistance to rice blast can be combined together, Can also be combined.
