Comparison of agronomic characters, total seed storage proteins and their use for genotypes discrimination in the Kentucky bluegrass (Poa pratensis L.)

This research aimed to investigate the genetic diversity among 11 Turkish Kentucky bluegrass (Poa pratensis) genotypes using seed storage proteins and agronomic traits. Thirty nine polypeptide bands in range of 10 to 82 kDa were recorded. Genetic similarity among genotypes was estimated basing on Euclidian coefficients. Cluster analysis was performed using the unweighted pair-group method with arithmetic averages (UPGMA). Similarity, coefficients of 11 genotypes belonging to Poa pratensis ranged 85-100% with low diversity of genetic variation in protein profiles. Average Euclidean distance used for agronomic data rangedfrom 1.51 to 8.11. This clustering pattern for protein profiles and agronomic data showed that same genotypes were revealed in same groups.
