摘　　要：对从国内外引进 ,经鉴定和比较抗旱、耐盐碱、矮杆性表现较好的 19份材料 ,进行了抗旱、耐盐碱比较试验 ,遗传相关和通径分析表明 :抗盐性与产量间呈负相关 ;第一棉铃高度与产量性状呈显著正相关 ,在主要的产量因素中第一棉铃高度 ,和单株结铃数对产量的通径系数最大 ,决定程度也最高。varieties with better characters after the determining and comparing to drought and salt resistance and dwarf characters in upland cotton varieties coming from abroad and domestic.The characters of 19 varieties were correlated and path analyzed . The result showed there were a significant a negative relation between salt resistance (under stresses 50 mmol·L -1 NaCl) and yields and also a significant positive relation between the first high fruit limb and yield. The first high fruit limb and the bolls plant are the decisive and the most contributive factor on the yield.
