Breeding,Main Characters and Application of Inbred Line Tongxi 5 of Waxy Corn

[Objective] The purpose was to modify and create waxy corn germ plasm resource,optimize the breeding basis groups,and breeding good inbred lines,to provide a guarantee for breeding single-cross hybrids with high yield and good quality.[Method] The breeding,main characters and application of inbred line Tongxi 5 of waxy corn were introduced,and its application and popularization value were discussed.[Result] Tongxi 5 and Tongxi 5 subgroup are the waxy corn inbred lines bred by the small group method which selects inbred lines from waxy-based groups directly in Agricultural Institute of Riparian of Jiangsu.These inbred lines has specialty of high combination ability and good comprehensive characters.They also combine more desired alleles from different waxy corns.The small group method is a nice expansion and supplement to recurrent selection.[Conclusion] A number of new waxy corn hybrids which mates with Tongxi 5 and its derived lines have been bred and had the features of high yield and good qualities.These series hybrids have been abroad applied in the production and had achieved good economic and social benefits.
