特种稻引种筛选试验

对11个引进水稻品种的生育期、主要农艺性状、产量及抗性进行了初步观测,结果表明:引进的11个地方特种稻基本适应南宁的自然环境条件,其中玉黄香、桂香4号、兆禾香表现出较好的农艺性状,其每667 m2的产量分别为453.2、445.6、432.6kg,明显高于对照及其他品种,有望成为本地特种稻的优良稻种;另外,玉黄香、象州红米、隆林地方糯3个品种对水稻纹枯病、稻瘟病及水稻螟虫都具有较高的抗性,可作为选育高抗性品种的优良稻种资源.

Introduction and screening test of special rice

The introduction of 11 local special rice varieties were observed by their growing periods, main agronomic traits, yield and resistance. The results showed that all of them basically adapted to the natural conditions of Nanning. Yu huang xiang, Gui xiang No.4and Zhao he xiang were better in agronomic traits, and the production were respectively 453.2 kg , 445.6 kg and 432.6 kg per 667 m2,significantly higher than the control group and other varieties. The three varieties are expected to become the excellence of local special rice. In addition,Yu huang xiang, red rice of Xiang zhou, and local glutinous rice of Long lin can be used as excellent rice resources of high breeding resistant varieties, which have a high resistance to the rice sheath blight, rice blast and rice stem borers.
