SELECTION INDEX AND THE RESOLUTION PRINCIPLE OF CORRELATED GENETIC PROGRESS

Yuan Zhifa Chang Zhijie,Yuan Zhifa Chang Zhijie,Yuan Zhifa Chang Zhijie

Abstract:

The essential idea of selection index is the resolution of correlated genetic progress produced by all of the selective traits. According to this principle,the construction of a selection index and the path coefficiency analysis can be joined together.

Key words: correlated genetic progress,selection index,path coefficiency analysis
