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一O.608—0.734,特殊配合力为-O.302~1.208;番茄红素的广义遗传力为57.35%,狭义遗传力为46.36%,其遗传符合加性一显性模型。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。
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.
