【摘要】 对广西1997年晚稻两系杂交水稻组合小区试验结果分析表明，15个参试组合中有7个组合比对照汕优63增产，增幅为1．01～12．31％，其中培S／杨选4号、培杂茂3、培杂茂选表现较突出，多数两系组合在品质、外观、株叶型、苗期耐寒性、耐肥抗倒性上，明显优于对照汕优63，而在结实率、充实度、灌浆速度等性状上，尚需进一步研究完善。更多还原

【Abstract】 The analysis of the plot experiment results of the two system hybrid late rice combination in Guangxi in 1997 Showed that,the output of the 7 combinations of the 15 combinations in the experiments increased comparing with the contrast - Shanyou 63. The increasing range was 1 .01 12. 3 %.
