摘要
对建国以来辽宁省水稻品种的系谱分析研究表明,在辽宁省常规水稻育种中做出重要贡献的主要亲本是丰锦、辽粳5号、辽粳326、辽粳294、辽粳454等。并提出水稻育种应以理想株型与有利优势利用相结合、优化性状组配为指导,以半直立穗型为选育新品种的形态指标,坚持以籼粳杂交后代的理想株型材料为桥梁种质,当地主栽品种为骨干亲本,采用多元复合杂交技术和多点生态选择的育种路线。
The pedigree analysis showed that since the establishment of China, the rice varieties that made the most important contribution to conventional rice breeding in Liaoning are Toyonishki, Liaojing 5, Liaojing 326, Liaojing 294 and Liaojing 454 et al. The effective means for rice breeding are the combination between ideal plant type and useful vigor, integration of optimized characters, taking semi-erect panicle type as morphological trait, and considering offsprings from cross between indica and japonica types as bridge germplasm and main varieties as elite parent. The technical mutes are multi-parent composite crossing and multi-location ecological selection.
