Fig. 4From: Identification of genetic loci associated with forage quality in response to water deficit in autotetraploid alfalfa (Medicago sativa L.)A hierarchical cluster obtained using farthest neighbor method with phenotypic values of all quality traits evaluated in the present study. Accessions (PIs) were clustered into 2 clusters (High and low quality clusters) and 14 subclusters. The high quality cluster contains 8 subclusters with relatively higher quality. The low quality cluster contains 6 subclusters with relatively lower quality. Two checks, “Saranac” and “Rambler”, susceptible to salt/drought stress were clustered into the high quality cluster (Subclusters 5 and 8, respectively), and three drought/salt resistance checks, “Mesa Sirsa”, “Wilson” and “Malone” were clustered into the low quality cluster (Subcluster 9)Back to article page
