Abstract
以25個穗著粒密度相異的稉稻品種（系）為材料探討11個稻穗構成性狀間的關係，結果發現一期作高單株產量之材料，具有穗重較重、一次枝梗平均粒數、二次枝梗數、二次枝梗總粒數、每穗粒數等較多、稔實率高與穗長較長等特徵，顯示穗型較大、粒數較多之材料，較能發揮高產之潛能：二期作高單株產量之材料群則為穗重、二次枝梗數、二次枝梗總粒數、每穗粒數與穗長中等者有較高產量表現。此外，一期作穗著粒密度雖與單株產量呈高正相關關係，然由主成份因子分布圖中顯示，高穗著粒密度者其單株產量並不一定高。Twenty five rice entries with different types of panicle density were used as materials to study the relationships between the 11 constructed characters of the panicle and grain yield per hill under Chaiyi environment conditions. In the first rice crop season, result revealed that entries with high yielding capacity pontenial were charactered by heavier panicle weight, a lot of average grain number per primary branch, secondary branch number per panicle, total grain number of secondary branches, total grain number per panicle, higher seed set and larger factor of panicle length. This might infer that the entries with high yielding pontenial in first crop season are largely due to heavier panicle weight and lots of grain number.
