摘要：

以16个具有代表性的中国南瓜自交系及其按Griffing双列杂交方法Ⅳ组配成的120个杂交组合为材料，对中国南瓜β-胡萝卜素含量的配合力进行了系统的研究，旨在了解不同南瓜自交系β-胡萝卜素含量的配合力特点。结果表明：在16个南瓜自交系中，从上海黄狼南瓜中选出的自交系‘百泉10’的一般配合力最大，其次是，‘百泉5’（来源于广东），‘百泉4’（来源于黑龙江）。最小的是‘百泉2’（来源于北京）。在120个杂交组合中，特殊配合力最大的是‘百泉9’（来源于河南）ב百泉10’（来源于上海），其次是‘百泉7’（来源于河南）ב百泉15’（来源于北京）、‘百泉4’（来源于黑龙江）ב百泉12’（来源于海南），最低的是‘百泉1’（来源于湖南）ב百泉11’（来源于江西）。因此不同来源的南瓜自交系间一般配合力差异很大。自交系间地理差异越大，其间的特殊配合力往往越高。

Abstract:

Sixteen inbred lines of Chinese pumpkins and 120 hybrid combinations which cross by the 16 inbred lines in Griffing Ⅳ were used to study combining ability of β-carotene content to understand the β-carotene content combing ability characteristics of different pumpkin inbred lines. The results showed that β-carotene content general combining ability (GCA) of Buan10 (from Shanghai) was the highest in the 16 inbred lines of Chinese pumpkins. The ‘Baiquan 2’ (from Beijing) had the lowest β-carotene content GCA. The β-carotene content special combining ability (SCA) of ‘Baiquan9’ (from Henan) × ‘Baiquan10’ (from Shanghai) was the highest in the 120 hybrid combinations. Secondly is ‘Baiquan7’ (from Henan) × ‘Baiquan15’ (from Beijing), ‘Baiquan4’ (from Heilongjiang) × ‘Baiquan 12’ (from Hainan). ‘Baiquan 1’ (from Hunan) × ‘Baiquan11’ had the lowest β-carotene content SCA. Difference of GCA was obvious for different sources of pumpkin inbred lines. The differences of geographical origin were more obvious, the SCA of two pumpkin inbred lines was often high.
