Some Morphological Characteristics Used in the Identification of Landraces Oat Genotypes in Central and Western Black Sea Region

Abstract

This study was conducted to collect, preserve and identify local oat genotypes grown in the Central and Western Black Sea region. Within the scope of the research, 251 local oat genotypes were collected from the places where they were cultivated in Düzce, Bolu, Zonguldak, Karabük, Kastamonu, Ordu, Sinop, Samsun, Amasya and Tokat provinces. The collected genotypes together with 4 standard oat varieties were taken into field trial in Ondokuz Mayıs University Faculty of Agriculture Research and Application field according to Augmented trial design in 2008 and 2009 growing seasons. As a result of the study, it was found that there were significant variations in terms of the parameters examined. Among the genotypes, the growth pattern of the 229 genotypes was perpendicular, The cluster genotypes of 163 genotypes were scattered, 132 genotypes were yellow in color, 157 genotypes were strongly stringy and 154 genotypes had callus hairiness. When the Matrix table was examined, it was found that the local genotypes with semi-horizontal growth pattern were not found in Amasya, Karabük, Kastamonu, Samsun and Tokat locations. In particular, parameters such as growth type, cluster type, color of husk, awn condition and callus hairiness. it provides ease of identification, since it does not affect the environmental conditions. In the light of this information, it is thought that the genetic variation is high in terms of ecology in which local genotypes are collected and will be beneficial for the protection of our genetic resources and for the future of national agriculture.
