加拿大玉米自交系改良黑龙江省杂交种的潜势分析
Genetic Potentiality of Canada Inbred Lines to Improve Heilongjiang Province Elite Hybrids
摘要
Abstract
The improved effect of 8 Canada introduced maize inbred lines by NCII design was analyzed to esti-mate the improved effect of introduced Canada maize inbred lines which in the same latitude with Heilongjiang province ,and to provide macro guidance for maize breeding .The results showed that inbred line C06 was con-sidered as the best at the aspect of comprehensive performance ,C05 was second .The better effect would be ob-tained by utilizing C06 in a breeding process of improved elite single-cross in many traits .C05 had the highest improved value on plant type traits ,and progress would be obtained by utilizing it to improve the plant type traits .The comprehensive performance of inbred lines C01 ,C02 ,C03 were in an average ,but C03 performed best than any other inbred lines at the aspect of improving kernel rows .The better effect would be obtained by utilizing C07 and C08 to improve the earliness of elite single-cross ,though the two inbred lines performed poor than other lines at other traits .Inbred lines C04 was the worst at the aspect of comprehensive performance ,and had no prominent improved superiority at other traits ,it could be eliminated .关键词
