不同青贮玉米品种品质性状与农艺性状的相关分析
Correlation Analysis of Agronomic Characteristics and Quality Traits of Different Silage Maize Varieties
摘要
Abstract
[Objective] The research aims to study the correlation between quality characters and agronomic characters of different silage maize varieties, and to provide basis for breeding high quality silage maize varieties.[Method]In the field experiment, a randomized block design was used to investigate the related agronomic traits, and the whole plant corn was collected at the end of the milk and the beginning of the early dough stage, and the related quality traits were determined.The correlation analysis was performed by DPS software.[Result]The content of crude fat was extremely significantly correlated with number of tillers(r=0.744,1**).The content of crude starch was extremely significantly correlated with height of tillers, height of ear of plant and number of ears(r=0.860,5**, 0.809,7**, 0.721,3**) respectively.The content of crude fiber was extremely significantly correlated with weight of stalk and weight of leaves(r=0.674,0**、0.600,9**).The content of both NDF and ADF were extremely significantly correlated with weight of stalk(r=0.835,8**, 0.805,0**).[Conclusion]The quality of the tillering silage maize was significantly higher than that of single stem silage corn, crude fat, crude starch were significantly higher than those of single stalk silage maize.The neutral detergent fiber and acid detergent fiber content was significantly lower than those of single stalk silage maize varieties.When indirectly selecting the quality traits, attention should be paid to the multi spike material, and other agronomic characteristics should be also considered to coordinate the relationship between yield and quality.关键词
