Abstract:
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,07-09,05-17 had the higher general combining ability,and were involved to produce high yielding hybrids(exceed standard＞30%),the value of Gx07-06,05991-1 that 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.
