| 摘 要： | 以超高产籼稻"满仓515"为对照,对"鄂荆糯6号"、"闽岩糯"、"越糯3号"3个常规高产籼糯品种的生物学特性、干物质积累与转运、产量及其构成进行了比较研究。结果表明,虽然这3个籼糯品种的穗数比"满仓515"多28.3%～56.3%,但总颖花数和库容量分别比"满仓515"少7.7%～20.6%和14.8%～30.4%,最终产量水平比"满仓515"低15.4%～22.1%。说明常规高产籼糯品种每穗粒数少和生物产量低是其产量较高产籼稻品种低的主要原因。

Comparison of Characters among High Yielding Indica Glutinous and Indica Rice Varieties |
| |
| Abstract: | The biological characters, accumulation and translocation of dry matter, yield and its components of three conventional high yielding indica glutinous rice varieties ("Ejingnuo 6", "Minyannuo" and "Yuenuo 3") were compared with those of high yielding indica rice variety "Mancang 515" (CK). The results showed that the number of spike of these three indica glutinous rice varieties was 28.3%～56.3% more than that of CK, but their total spikelets, sink capacity and terminal yield were 7.7%～20.6%,14.8%～30.4% and 15.4%～22.1% less than those of CK respectively. According to these, less grains per spike and lower biological yield of the conventional high yielding indica glutinous rice varieties were the key reasons why they had lower yield than high yielding indica rice variety. |
