| 中文摘要 | 在秈稻43個品種中探討秈稻穀粒外部性狀與碾米品質對完整米之相關 ,第一期作有白米率與完整米率呈顯著正環境及遺傳相關,第二期作作糙米率及 白米率與完整米率呈極顯著正環境相關,粒長與完整米率呈顯著負遺傳相關,粒 厚及白米率與完整米率呈極顯著正遺傳相關,所以第二期作對秈稻完整米率選拔 比第一期作有效,第一、第二期作完整米率之遺傳率均大。 |
| 英文摘要 | The correlations of grain morphological characteristics and milling quality with the percentage of head rice were measured for 43 indica varieties. It was found that the environmental and genetic correlation of the percentage of total milled rice were significantly correlated with the percentage of head rice in the first crop. In the second crop, the environmental correlation of the percentage of brown rice and total milled rice had a significantly positive correlation with the percentage of head rice; grain length had a significantly negative genetic correlation with the percentage of head rice; grain thickness and the percentage of total milled rice had a significantly positive genetic correlation with the percentage of head rice. Therefore, selecting the high percentage of head rice was better in the second crop than in the first crop. The heritability of the percentage of head rice both at the first crop and second crop were large. |
