- 摘要:
- 为了构建寒地超级稻的理性株型，对松粳9号、龙稻11、龙稻5号、龙粳21、龙粳31和龙粳20，6个寒地超级稻品种的产量构成因素与产量的关系进行研究。结果表明：寒地超级稻的单株分蘖和着粒密度差异不显著，是寒地超级稻的共性性状。株高、千粒重、每穗实粒数、穗长等性状品种间差异显著，但有规律可循。株高、千粒重和穗长与单株穗重呈极显著正相关关系。
- Abstract:
- In order to establish the ideal plant type in cold region,the relationship between yield component and yield of six varieties of super rice included Songjing 9,Longdao 11,Longdao 5,Longjing 21,Longjing 31 and Longjing 20 in cold region were studied.The results indicated that the plant height,1000 grain weight,the full filled grain number per panicle and panicle length had great significant difference except for the tiller number per plant and grain density.The plant height,1000 grain weight and panicle length had significantly positive correlated with the panicle weight per plant.
