【Abstract】 In 1996～1997, an investigation was made of the germplasm resources of rice in 13 counties of the Three-Gorges Reservoir Area. A total of 104 accessions were collected and then grown in field trials in Chongqing Sanxia Institute of Agricultural Sciences, and their agronomic characters were evaluated. Some genotypes with high yield per plant, or big panicles, or large seed size, or high 1000-seed-weight, or other special characters were identified and recommended for direct utilization in cultivation or indirect utilization in rice breeding.更多还原
