Description
Summary:The characterisation and evaluation of the available maize germplasm is a necessary first step to facilitate breeding efforts. Eighteen maize accessions (labelled as AGB plus number), each part of the Albanian Gene Bank collection, were characterized by agro morphological descriptors. An estimated 25 morphological traits (15 quantitative and 10 qualitative) were based on the IBPGR Descriptors for maize. Variation of morphological characteristics among accessions ranged from 5.63% for days-to-tasseling to 24.29% for ear height. The analysis correlation coefficients among descriptors showed a positive significant association between days-to-silking and days-to-tasseling, and a positive correlation was observed, between the number of kernels per row and ear length traits. Morphological relationships among 18 genotypes were clarified on a dendrogram by the complete linkage method. Results from the hierarchical cluster analysis show that, there is significant variation among the 18 genotypes, suggesting that the maize germplasm collection of the Albanian Gene Bank is a rich source of material, with adequate variation for future use in breeding programs.
