| 摘 要： | 1998年早季在广州研究了3个两系法杂交水稻组合和2个常规稻品种的产量构成因素,初步认为:两系法杂交稻新组合培矮64s/E32的产量最高,它单穗湿重和穗长亦最大,分别达5.42g和24.7cm;而常规稻品种粤香占亩有效穗数最高和谷/秆比值最大,分别达23.3万穗/亩和1.53。如果把这些性状有机地组合起来后再加上粤杂122的优质特性,这种结构模式将为华南地区水稻超高产或超级稻育种,展示了一种美好的前景。

| Abstract: | The yield components of 3 two-line rice hybrids and 2 inbred varieties were studied at Guangzhou in the early cropping season of 1998. The results showed that the two-line rice hybrid Peiai 64s/E32 gave highest yield, the heaviest individual fresh panicle weight and longest panicle length reached 5.42 g and 24.7 cm, respectively. However, the inbred rice variety Yuexiangzhan had both greatest number of productive tillers and grain/straw ratio, being up to 3.495 million panicles per hm2 and 1.53 of grain/straw, respectively. If these traits mentioned above and fine kcrnal quality of Yueza 122 could be integrated to form a new plant type, it would exhibit an excellent prospects in breeding for getting super high yield in South China rice cropping regions. |
