摘要
研究了籼爪交和粳爪交杂种在长沙、三亚两地农艺性状和干物质产量的表现。由引进爪哇稻品种所配的籼 /爪和粳 /爪交杂种 F1 代表现为植株高大 ,生长茂盛 ,具有强大的干物质产量优势。绝对干物质产量 (单株穗期干重 )为 :籼爪杂种 >粳爪杂种 >对照 (籼籼交杂种 ) ,干物质生产率 (单株日干物质产量 )为 :籼爪杂种 >粳爪杂种 >对照。供试籼爪交和粳爪交组合感光性较强。
The agronomic traits and dry matter production of indica/javanica and japonica/javanica hybrid rice at Changsha and Sanya were studied. The F 1 hybrids show taller plant type and plentiful growth, possess high dry matter production advantage over check hybrid. The dry weight per plant at heading stage of indica/javanica hybrid is the heaviest and that of japonica/javanica hybrid is heavier than that of check hybrid. The daily dry matter production per plant of indica/javanica hybrid is heaviest and that of japonica/javanica is heavier than that of check hybrid. The F 1 hybrids studied are sensitive to photoperiod.
