Abstract

Abstract:

【Objective】 To study the effects of salt and alkali stress on the emergence rate, growth rate and yield of peanut with high oleic acid. 【Methods】 In this study, 34 varieties (lines) of peanut with high oleic acid were used as materials to record the changes of seedling emergence rate, agronomic traits and growth rate of peanut with high oleic acid planted in saline-alkali land, in order to provide data support for screening peanut varieties suitable for planting in saline-alkali land. 【Results】 Under saline-alkali stress, the seedling emergence rate of Jihua 18 was the highest, and that of Jihua 9 was the lowest. The growth rate of main stem height of flowering 910 was the fastest, and that of Kainong 1760 and P19-24 was the slowest. The growth rate of peanut decreased with the extension of growth period. At the same time, the yield of high-oleic acid peanut was significantly inhibited by salt-alkali stress. Yuhua 37, Kainong 1715 and Huayu 9130 had the highest relative yield and better salt tolerance. Different varieties (lines) had great differences in different identification indexes. 【Conclusion】 The comprehensive evaluation value of salt and alkali resistance is obtained through membership function analysis, and cluster analysis carried out. 34 materials divided into 4 categories, and the first category belongs to 1 material with high salt and alkali resistance. The second category belongs to 7 saline-alkali strong material; the third category belongs to 15 salt-resistant general materials; The fourth category belongs to 11 salt sensitive materials

Key words: high oleic acid peanut; whole growth period; resistant to salt and alkali; comprehensive evaluation

摘要：

【目的】研究盐碱胁迫对高油酸花生出苗率、生长速率、产量等影响,为筛选出适宜盐碱地种植的高油酸花生品种提供数据支持。【方法】以34份高油酸花生品种(系)为材料,记录高油酸花生在盐碱地种植下的出苗率、农艺性状以及生长速率等的变化。【结果】盐碱胁迫下,冀花18出苗率最高,济花9号出苗率最低;开花期-下针期,花育910主茎高生长速率最快,开农1760和P19-24最慢;随着生育期的延长,花生生长速率呈下降趋势;同时盐碱胁迫显著抑制高油酸花生产量,豫花37、开农1715和花育9130相对产量最高,耐盐性较好。不同品种(系)在不同鉴定指标上存在较大差异。【结论】耐盐碱性综合评价值,并进行聚类分析,将34份材料划分4类,第1类属于高耐盐碱材料1份;第二类属于耐盐碱较强材料7份;第三类属于耐盐性一般材料15份;第四类属于盐敏感材料11份。
