| 摘 要： | 对2个普通小麦品种群体及5个杂种组合后代群体植株各穗子的正常小穗数(x1)和基部退化小穗数(x2)之间的相关性、退化小穗数比率在株间和株内变异进行了研究。相关分析表明正常小穗数与退化小穗数之间存在极显著的负相关性,即当退化小穗数增加时,正常小穗数有极显著减少的趋势。方差分析表明,发育差异和遗传差异对退化小穗比率影响均很大,要减少退化小穗比率应同时考虑发育和遗传两个因素。

| Abstract: | The relationship between numbers of normal and degraded spikelets in 2 varieties and 5 progeny populations of common wheat were studied.The simple correlation analyses indicated that there are much significantly negative correlation between numbers of normal and degraded spikelets,that is,the more the degraded spikelets and the less the normal spikelets.The variance analyses showed that there are significantly effects of both genetics and development on degraded spikelet number.It is necessary for reducing ... |
