Title
Evaluation seed vigor diversity of barley (Hordeum vulgare) lines
Authors
Abstract
In order to evaluate seed vigor diversity of barley lines in field, an experiment was conducted with 72 lines as randomized completely block design. Germination uniformity, mean germination time
(MGT) germination rate and seedling height were measured. Results indicated that MGT, germination rate were significantly different among different lines. The results showed variation in germination of different lines. Cluster analysis in 72 lines showed 4 clusters. The forth cluster had lowest seed germination percentage and rate. The second cluster with the highest seed germination percentage and rate was superior though could be used in further experiment to produce the seeds with higher seed vigore.
