摘要： 以5个番茄自交系为材料,完全双列杂交设计,对番茄果实中番茄红素配合力及其遗传参数进行了分析和估算。试验表明:番茄红素的一般配合力为-0.608~0.734,特殊配合力为-0.302~1.208;番茄红素的广义遗传力为57.35%,狭义遗传力为46.36%,其遗传符合加性—显性模型。所以在育种中采用系谱选择以提高和固定高番茄红素性状是有效的,有性杂交育种可在早期世代进行选择。

Abstract: The combining ability and genetic parameters of lycopene content in tomato fruits were studied by means of the first method of Griffing's dialles cross.The main results are as follows :the general combining ability was among-0.608 -0.734,and the special combining ability ranged in -0.302 —1.208.The broad sense hereditability of lycopene content in tomato fruit was 57.35 %, the narrow gene hereditability was 46.36 %, and due to additive -dominant model.
