摘要: 为了筛选花生抗旱性鉴定评价指标,构建评价体系,利用177个株系组成的花生重组自交系群体为研究对象,连续2年在充分灌溉和干旱胁迫条件下种植,收获考种后分析了22个表型性状、2个生理指标与抗旱系数间的相关关系。结果表明:总分枝数、结果枝数、结果节数、单株果数、百仁质量这5个表型性状的干旱胁迫指数以及叶绿素含量、冠层温度2个生理指标的抗旱性综合评价值均与抗旱系数有显著相关关系,这7个性状可作为判定花生抗旱性的评价指标。以抗旱系数≥1.1为标准,筛选到3个抗旱株系,即L19、L121和L146。

Abstract: The objective of this article was to screen the drought resistance identification indexes and build evaluation system of peanut.In this study,a RIL population consisting of 177 lines which were planted in well-watered and drought stress environments in 2 years was analyzed based on 22 agronomic traits and 2 physiological characters.To detect the drought-resistant identification indexes,the correlation between these traits and the drought coefficient were analysis.The results showed that the correlation between drought coefficient and stress index of number of branch,number of bearing branch,number of bearing node,number of pods per plant,100-seed weight,comprehensive appraisal D value of chlorophyll content and canopy temperature were showed significant level.So these 7 traits can be used to screen drought-resistant germplasm.Drought-resistant germplasm were identified using a minimum drought coefficient score of 1.1.Using this criterion,steady drought tolerant lines L19,L121,L146 in the population were screened out.

Key words: Arachis hypogaea, Drought resistance, Drought coefficient, Stress index, Comprehensive appraisal
