Abstract:

Factorial diallel matings were carried out in 1982,1989 and 1991 by using excellent clones of Cunninghamia lanceolata and some clones of old C. lanceolata as parents and 58 matches were obtained which were used to build 3 control-pollinated progenies tests. According to the analysis of variance and quantitative genetics for control-pollinated progenies tests,the preliminary result was that it was a good choice to use excellent clones of C. lanceolata as female parents and to use clones of old C. lanceolata as male parents. Four excellent female parents including Jian36,Wangtai,Minqing1 and Youxi and 3 excellent male parents including Jian36,San67 and Minqing1 were selected respectively. Based on the comparative analysis and evaluation of the performances of 58 matches,6 excellent matches including San54×Min1,Wangtai×San66,Min1×Jin8,Min2×Jian36,Min1×San67 and Youxi×San67 were selected. They were very striking in production and could be used for advanced generation seed orchard or applied in vegetative propagation. These matches also could be used for advanced generation breeding.
