PHENETIC STUDIES IN AVENA SPECIES AND POPULATIONS OF IRAN
نویسندگان: ثبت نشده
چکیده مقاله:
A multivariate statistical analysis was performed on morphological characters of sixty-one populations of Avena eriantha Dur. A. clauda Dur., A. barbata Pott ex Link., A. wiestii Steud., A. fatua L., A. sterilis ssp. ludoviciana L. and A. sativa L. Factor analysis revealed that intraspecific morphological variations are due to quantitative characters. Interspecific as well as intersectional relationships were investigated using cluster, discriminant analysis and ordination method based on principal components supporting the Baum’s classification.

متن کاملMEIOTIC STUDIES OF SOME AVENA SPECIES AND POPULATIONS IN IRAN
Eleven populations of five Avena species were analysed for meiotic characters including chiasma frequency and distribution as well as chromosomal association and segregation. Plants of a single population of A. eriantha showed the presence of 2n = 14 (diploid) and 2n = 4x = 28 chromosome number. Populations of A. barbata and A. wiestii possessed n = 14, while populations of A. sterilis ssp. lud...
