摘要:

为筛选出适合内蒙古兴安盟地区种植的耐盐碱水稻种质资源,以内蒙古推广及引进的102份水稻种质资源为材料,在水稻栽培过程中进行盐碱胁迫处理,通过分析死叶百分率、耐盐碱指数、农艺性状及产量来综合评价供试材料的耐盐碱性强弱。结果表明,长白9号、绥粳26、乌兰105、吉农大538、松辽5号和松辽186等品种表现出很好的耐盐碱能力及良好的丰产性,可以作为耐盐碱资源加以利用。

Abstract:

In order to screen out the saline-alkali-tolerant rice germplasm resources suitable for planting in Hinggan League area of Inner Mongolia, we comprehensively evaluated the saline-alkali tolerance of 102 rice germplasm resources promoted and introduced in Inner Mongolia by analyzing the percentage of dead leaves, aline-alkali hazard index, yield traits and agronomic traits. The results showed that Changbai 9, Suigeng 26, Wulan 105, Jinongda 538, Songliao 5 and Songliao 186 performed high saline-alkali tolerance and yielding ability, which could be used as saline-alkali resistant resources.

Key words: rice, saline-alkali tolerance, germplasm resources, screening
