The relationship of grain quality characters between F1 hybrid and their parents of indica rice were studied. The grains of F, hybrids from high/intermediate and high/low amylose content (AC) had intermediate AC. Selecting the variety Qiguizhao with intermediate gel consistency (GC), intermediate gelatinization temperature (GT) and long kernel as female would help to obtain F1 hybrids with soft or intermediate GC and intermediate GT, and to increase their fat content and kernel length. The crosses between different inferior quality cultivars would produce F1 hybrids with poor quality. In the present study Qiguizao/Xinsimiao, Qiguizao/Jinzhan and Qiguizao/Zaoyouzhan would be the best combinations for superior quality and high yield. It is more possible to derive superior quality and high yield F1 hybrids from combinations of superior/superior and superior/inferior quality.
