摘要
利用9个不同生态类型的59份粳稻亲本材料,以生态型为单位进行双列杂交,配制303个组合,研究各生态类型和杂种主要品质特性。双亲中值和对照值的分析表明,各类型中华北粳、日本粳和韩国粳为亲本的生态组合不仅表现出较高的整精米率,而且高整精米率出现的比例大,高整精米率组配模式为西北粳×日本粳、华北粳×台湾粳、东北粳×韩国粳和华北粳×韩国粳。
Total 59 Japonic rice lines from 9 ecotypes were used as materials in this study, and main quality characters of F1 hybrids of 303 combinations created in a diallel set of cross were analysed. Statistical analysis showed that F1 hybrids of cross combinations, using North China, Japanese or Korean as parent, produced higher head rice rates than other ecotypes, and had higher percentage of combinations with high head rice rate, compared with the other ecotypes. Cross combination patterns of high head rice rate are Northwestern × Japanese, North China × Taiwan , Northeastern × Korean and North China× Korean, respectively. The results benefit cross-combining and parent-selecting in high head rice rate breeding.
