Grey Correlation Degree Analysis between Main Agronomic Characters and Yield of Early Rice in South Hunan Hills |
| |
| Abstract: | The correlation between 6 main agronomic characters and yield from “3415” ifeld fertilizer experiment in south Hunan hills were analyzed by grey correlation degree analysis. The results showed that the decisive factors to decide the early rice yield among the 6 main agronomic characters in hilly region of southern Hunan Province had the following order: plant height, number of productive ear, total grain number per panicle, ear length, thousand seed weight, and iflled grains number per panicle. |
