ABSTRACT

Compared with other crops, peanut planting costs are lower, and it is very drought-tolerant, and can obtain better benefits. In this paper, 16 peanut varieties were selected, and drought resistance tests were carried out at the flowering and cutting stage under water stress conditions. The root characteristics related to drought resistance of peanuts and the physiological mechanism of drought resistance of different varieties were studied to screen peanut varieties with better drought resistance. According to the relative value (RV) of each trait, the drought resistance coefficient (DC) and drought resistance are calculated. The results show that A596, NC6, Shanhua11 and shanhua7 have strong drought resistance, Shanhua12, Nongda 818, Shanhua 8, Huayu 20, Haihua 1, 79266, Shanhua 9, Hua 17 have moderate drought resistance, while Jihua 4, Guihua 836 , ICG6848 and Baisha1016 have weaker drought resistance.

摘要

与其他作物相比，花生种植成本较低，而且非常耐旱，可以获得较好的效益。本文选择了16个花生品种，在水分胁迫条件下，在花期和扦插期进行了抗旱试验。研究与花生抗旱性相关的根系特性及不同品种抗旱生理机制，筛选出抗旱性较好的花生品种。根据各性状的相对值（RV），计算抗旱系数（DC）和抗旱性。结果表明，A596、NC6、山花11和山花7具有较强的抗旱性，山花12、农大818、山花8、华玉20、海花1、79266、山花9、华17抗旱性中等，而冀化4、
