Abstract

Abstract: 【Objective】 To breed a group of silage maize germplasm resources suitable for planting in Hulun Buir region of Inner Mongolia,in order to alleviate the problems of silage maize germplasm resources shortage and narrow foundation.【Methods】 The quality and agronomic traits of 114 silage maize inbred lines were screened and evaluated by factor analysis.【Results】 Eleven silage maize inbred lines were selected,which were G117,1459-2s6,15300a-1,17100-2s3,1479,13246,DK269,1785bS3,NYW1501B,1776-2s4 and 17115bS3.Among them,9 of them met the first-grade standard of silage maize quality grade （national standard）,and 2 of the inbred lines met the second-grade standard.【Conclusion】 The selected inbred lines can be used as good silage maize resources to cultivate high quality silage maize hybrids.
