摘要: Thirteen hybrid paddy rice varieties were used for the studies on the effects of latitude on the grain yield and quality in three rice planting areas. The results showed that the effective panicles and seed setting rate had biggest difference. The grain yield in Yunan Mile was 744.27 kg/667 m(2), which was higher (22.49 and 40.62%, respectively), compared with Sichuan Wenjiang and Shanxi Hanzhong, the differences among them achieved significant level. The head rice rate, chalky rice rate and GC showed significant difference alongwith latitude changed, as far as milling and appearance quality were concerned. These hybrid paddy rice varieties in Sichuan Wenjiang were better, as far as cooking and nutrition quality were concerned. These hybrid paddy rice varieties in Shanxi Hanzhong were better. Synthesized yield and quality, D you 527 was adapted to plant in three rice planting areas of different latitude than others.
