摘要: 引进斯里兰卡水稻种质资源166个在四川雅安生态条件下进行种植,进行形态和品质等性状的观察和测定。并以国内8个不育系作母本,135个生育期适中的引进材料作父本,开展了测交筛选工作。结果表明,4个组合在产量上具有明显的杂种优势,34个材料的测交后代结实良好,15个材料的测交后代表现为不育

Abstract: The rice germplasm resource introduced from Sri Lanka was planted under ecological condition of Yaan city in Sichuan, some agronomic traits and gain quality traits were observed and determined. As pollen parent, 135 introduced materials of moderate age from sowing to heading testcrossed with 8 China's CMS, testcross progenies were screened for pollen sterility/fertility, spikelet fertility and other agronomic traits. The results show that output of 4 testcross progenies are higher than the check varieties respectively, and 34 testcross progenies are spikelet fertility and 15 testcross progenies are sterility.

Key words: rice, germplasm resource, testcross, screening
