摘要: 调查了26份高原粳稻品种(系)的田间抗倒性,测定了材料的株高、穗重、穗长、节间长度、节间壁厚、节间直径与节直径7类共20个性状,同时分析了品种抗倒性与系谱之间的关系。结果表明, 穗长、穗重与节间直径3类性状与抗倒性相关不显著,株高、穗下节间长度、穗下节间壁厚、穗下节直径这4类性状与品种抗倒性显著或极显著相关;品种系谱分析表明,品种(系)的抗倒性与其亲本关系密切。品种抗倒性与其亲本关系密切,选择抗倒伏品种作亲本,可以提高育成品种的抗倒性。

Abstract: Lodging resistance of  26 varieties and lines of plateau japonica rice was evaluated by investigating  20 traits(7 classes) including plant height, panicle  weight, panicle  length,    internode  length,    internode  wall thickness,   node diameter etc. The relationship between lodging resistance and pedigrees of the rice varieties  was analyzed. The results showed lodging resistance was not significantly correlated with    panicl  length,    panicle weight, and     internode diameter,  while significantly correlated with the rest 4 classes of   traits. Pedigree analysis showed  lodging resistance of varieties was closely correlated with that of  their parents.   Among there traits,   plant height,    internode lengths,  thickness of internode wall, and   diameter of node have significant correlation  with lodging resistance.   Lodgingresistant parents help improve lodgying resistance of  bred varieties.

Key words: plateau japonica rice, lodging resistance, agronomic traits, correlation, pedigree analysis
