Agronomic Characteristics and ISSR Molecular Marker Analysis of Different Alfalfa Varieties

doi:10.7668/hbnxb.2014.03.021

Abstract

Abstract: The article was mainly studied from agronomic characteristics and ISSR molecular markers of alfalfa.Analyzed from the correlation of eight agronomic characteristics of alfalfa, it was found that fresh yield of alfalfa was closely related to plant height and rate of regrowth, and hay yield of alfalfa was not only related to plant height and rate of regrowth, but also closed with ratio of dry weight to green weight.By cluster of eight agronomic characteristics and ISSR amplification results, 26 alfalfa varieties were divided into four groups with methods, the cluster result of agronomic characteristics was mainly related to adaptability to local conditions and fall dormancy level of different alfalfa varieties, however, the cluster result of ISSR molecular markers was mainly related to genetic background of different alfalfa varieties.

Key words: Alfalfa, Agronomic characteristics, ISSR molecular marker, Cluster analysis
