Agro-Morphological Characterization of Wild Crambe (Brassicaceae) Species In Turkey
ILHAN SUBAŞI
Abstract
A number of species and subspecies of the genus Crambe of the family Brassica, which contains 6 species and 4 subspecies from 35 taxa registered worldwide, naturally grow in Turkey. In this study, 48 germplasm accessions, belonging to 3 Crambe species in native flora of Turkey, were collected and their morphological characteristics were examined. The accessions were grown under field conditions. Various morphological data (plant height, number of branches per plant, number of seeds per plant, yield per plant, 1000 seed weight, and hull/whole seed percentage) were determined. The present collection showed significant phenotypic diversity in terms of the examined morphological characteristics. Variations in the morphological characteristics were analyzed using principal component analysis. In the factor analysis of Crambe maritima, Crambe orientalis, and Crambe tataria and species averages, the first 2 components accounted for 100%, 68.57%, 62.14% and 100% of the total agro-morphological variations, respectively. There were positive and negative correlations among the agro-morphological features. These findings showed a number of important traits in the gene pools and a wide variation in the phenotypic data, which provided a good source of diversity for breeder-specific aims.
