Abstract: In order to breed two infertility lines, with low temperature of infertility starting point, strong combining ability and fine grain quality, the author analyzed yield, quality, diseases and pests resistance of 22 Y58S combinations bred in recent years. The results showed that the average yield was 8978.7 kg/hm2. 40.9% of the tested combinations had all quality indexes reached standard level-3 of “high quality rice”, but the combinations were sensitive to rice blast and brown planthopper. Therefore, the tested combinations had high production level and excellent quality, but relatively poor diseases and pests resistance.
