甜椒主要数量性状配合力研究

Studise on the Combining Ability of the Main Quantitative Characters in Sweet Pepper

本试验选用６个甜椒品种，采用完全双列杂交１／２Ｐ（Ｐ—１）模式设计，统计分析了６个性状的一般配合力效应和特殊配合力效应，结果表明：（１）６个性状的一般配合力方差和特殊配合力方差均达到极显著水平。（２）产量、单果重、结果数、花期一般配合力效应最高和最早的分别为哈椒一号、上海甜椒、女姑椒和辽椒一号，特殊配合力效应值最高和最早的分别为，产量、结果数均为Ｃ×Ｅ、单果重为Ａ×Ｂ、熟期最早为Ｅ×Ｆ。

A set of diallel crosses involving six sweet pepper varieties,according to the 1/2P(P - 1)type,was made to study the general combining ability and special combining ability of six characters.The results indicated that: a) The X2 values of these characters of general combining ability and special combining ability all reached extreme significant level,and b) amons general combining abilities of yield, fruit number, weight of single fruit and bloomillg period, the highest and earliest were Harbin sweet pepper No. 1,Shang Hai sweet pepper,Nu Gu sweet pepper,Liao Sweet pepper No. 1. Among the spelial comibining abilites,the highest and earliest were C ×E for yield and fruit number, A × B for single- frait weight, E ×F for maturation period.
