摘  要：
以1份黄色线辣椒材料为母本,10份红色线辣椒为父本,采用顶交法配制10个杂交组合,研究了果实成熟色和8个农艺性状的杂种优势和配合力。结果表明:所有F1代果实成熟色均表现红色,红色果实成熟色相对黄色而言为显性效应;F1代除开展度外各性状均表现出正向优势,具有较高的超中亲、超高亲以及超标优势;一般配合力效应值与杂种优势表现呈正相关,Gx07-06、05991-1、xhB、07-09、05-17产量性状一般配合力相对较高,参与组配的组合为强优势组合,超标优势>30%,Gx07-06、05991-1超标优势分别达到75%和56%,为高产优质亲本;可利用此类亲本组配高原环境气候下高产线辣椒品种。

摘  要：
One yellow chill pepper and ten common red chill peppers were used for the eleven incomplete top-cross.The heterosis of each character,general combining ability was analyzed based on the data from field experiment and were used to classify heterotic groups by analyzing general combining ability of eight agronomic characters.The results indicated that the heterosis was ubiquitous and positive advantages were performed in most characters.All the characters except its canopy showed a positive heterosis,having a higher positive heterosis over mid-parents,better-parents and standard heterosis.General combining ability and heterosis value was positively correlated,the yield trait of Gx07-06,05991-1,xhB,07-09,05-17had the higher general combining ability,and were involved to produce high yielding hybrids(exceed standard>30%),the value of Gx07-06,05991-1that exceeded standard was 75%and 56%,both of them were good parents with high yield,which could be used to produced the new varieties of chill pepper under the environment of Qinghai-Tibet plateau.
