摘要:
为探索栗属杂交F1代幼林期叶片性状遗传变异规律及杂种优势,以板栗、锥栗种内和种间9个杂交组合235个杂交单株及其亲本为研究材料,利用巢式方差分析、Pearson相关性分析及主成分分析等统计学方法对其14个叶表型及光合生理性状进行分析。结果表明:①栗属杂交F1代叶表型及光合生理性状存在丰富的遗传多样性,14个性状平均变异系数范围为4.40%~27.76%;②性状组合间表型分化系数VST均值为32.32%,组合内变异是主要的变异来源;③性状中亲优势率为-27.16%~90.53%,且不同组合性状杂种优势存在差异;④Pearson相关性分析结果显示14个性状中分别有46对和13对相关性达到极显著(P<0.01)和显著水平(P<0.05),其中叶长、叶宽等5个叶表型性状及叶绿素a、叶绿素b等4个光合生理指标相互间影响较大;⑤利用主成分分析法筛选出“魁栗×YLZ 15号”和“魁栗×YLZ 1号”两个优良杂交组合,其子代叶片具有叶面积大、干物质含量及光合有关色素含量高的特点,可为进一步筛选优良杂交子代提供主要素材。
