摘 要 ：利用3对糯与非糯近等基因系研究了糯质基因(wx)对产量构成性状的影响。3对糯与非糯品系均仅具有千粒谷重这一产量构成性状有极显著的差异,糯稻比非糯稻降低7.3—9.7%,降低的原因并非由于谷粒体积的减小而是由于糙米粒重和谷粒比重的降低。糯稻与非糯稻具有相同的同化产物库容,但由于灌浆不充实,米粒较小,导致糯稻谷壳内余留较

Abstract:Effects of waxy gene on yield components in Oryza sativa L.sp.indica were studiedusing three pairs of waxy and nonwaxy near isogenic lines,Guangluai 4,Yuanfengzao andZhenzhu 19.There were no significant differences between each pair of them except that1000 grain weights were 7.3—9.3% lower in waxy
