Abstract

Morphological characteristics of ear were used for estimation of genetic diversity in 50 varieties of hexaploid winter wheat originated from Croatian breeding programs. Field trials were set at two locations in two vegetation years (2008/09 and 2009/10). Observations in field trials and laboratory were done on 13 ear characteristics used in DUS testing. Genetic diversity research of Croatian wheat germplasm according to ear morphological characteristics, showed a high level of dissimilarity (0.625) among the tested varieties. Varieties Super Žitarka and AFZG Karla are pointed out with highest coefficient of dissimilarity (0.94). Application of UPGMA method showed that all varieties in different groups had significant genetic diversity. On the basis of data analysis the most distant varieties with the best morphological characteristics of ear were determined and it will be help in the selection of new parent combinations in future breeding programs.
