| 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. |
