比较了滇型杂交粳稻、云光两系杂交粳稻、外引两系杂交粳稻、常规粳稻的产量和主要源库性状,结果表明,杂交粳稻产量和主要源库性状比常规粳稻具有极显著优势,滇型杂交粳稻的产量和库容量较两系杂交粳稻具有极显著优势,云光两系杂交粳稻与外引两系杂交粳稻具有相近的产量和库容量。滇型杂交粳稻结实率较低,上3叶面积等源性状存在劣势,表现出库大而源相对不足的特性。
The yield and main source and sink traits of two japonica hybrid rice lines of Yunnan, Yunnan and Yunnan were compared. The results showed that the yield and main source-sink trait of japonica hybrid rice had extremely significant advantages over conventional japonica rice, The yield and storage capacity of Dian type japonica hybrid rice had extremely significant advantages compared with that of two-line japonica hybrid rice. The two lines of two-line hybrid japonica rice had the similar yield and storage capacity. Dian-type hybrid japonica rice had lower seed setting rate, lower isofertal traits in the upper 3 leaf area, and showed the relative lack of large-scale source.
