Correlation Analysis about Agronomic Traits and Yield of Rape Varieties with Different Maturity Stages
摘要
Abstract
Early and middle maturing rape varieties which were participated in the national regional test of the middle Yangtze river region during 2012-2011 years and 2012-2013 years were used as materials.The agronomic traits of the rape varieties,include growth period,plant height,effective branching position,the number of effective branch of the first time,main inflorescence length,inflorescence pods,the number of effective pods per plant,grain number per pod,thousand grains weight and yield,were collected.Correlation and path analysis were used to study the relationship between agronomic characters and yield of the rape varieties with different maturity stages.Results showed that the correlations of the yield of early maturing varieties with main inflorescence length,the number of main inflorescence pods and the number of effective pods per plant,thousand grains weight were significant.The correlations of the yield of middle maturing varieties with agronomic traits were not significant.Thousand grains weight showed the biggest direct effect on the yield of early maturing rape varieties,and main inflorescence length showed the biggest indirect effect.Plant height showed the biggest direct effect on the yield of middle maturing rape varieties,and the number of effective pods per plant showed the biggest indirect influence.关键词
