【Abstract】 With the introduction of five Chinese hybrid rice combinations to Pakistan.The results have shown that the growth duration of hybrid rice was 5～10 days shorter than that of local varieties, and had obvious advantage in grain yield over local varieties, with the increase of the number of filled grains per panicle ranging between 30～98, 1 000～grain weight 0.7～3.5 g,the weight per panicle 9.78%～69.56%.The average yield of hybrid rice was 30% higher than that of local varieties.Besides, hybrid rice had better grain quality than local varieties, especially in cooking quality.更多还原
