| 摘 要： | 以扬稻6号、明恢63、特青3个著名恢复系与广占63-4S、培矮64S、粤泰A等3个具有代表性的不育系配制杂交组合,研究扬稻6号作为骨干恢复系的配组优势。结果表明：扬稻6号与明恢63、特青相比,配制的组合具有明显的生物产量优势和经济产量优势;顶3叶叶姿挺拔,基部节间坚实,抗倒力强;高效叶面积率高;具有高根系活性和光合生产能力。并讨论了扬稻6号在杂种优势上的利用价值。

| Abstract: | Using Yangdao 6,Minghui 63 and Teqing(three famous restorers) and Yuetai A,Pi64S and Guangzhan63S(sterile lines) as parents,hybrid rice combinations were established and Combining Predominance of elite restorer lines "Yangdao 6" were studied.The results showed that: compared with Minghui 63 and Teqing,the combinations which were compared with the elite restorer lines "Yangdao 6" had obvious advantages in biomass and economic production and significant difference in yield;the leaf distribution of top three l... |
