Abstract

By applying multivariate statistical analysis, this research aimed to estimate the heritability and find relationships between the vegetative and reproductive characteristics of Prunus scoparia and Prunus elaeagnifolia. Twenty genotypes of each species were selected randomly from cultivated populations and twenty-two traits including the tree, leaf, flower, nut and kernel attributes were measured. Results showed that there were high levels of genotypic and phenotypic variations among the genotypes of both species. Many of the measurements pertaining to the leaf, flower, nut and kernel, showed very high heritability (H2 >90%) in both species, whilst some traits such as shoot diameter in P. scoparia and kernel moisture in both species had very lower heritability (H2 <50%). Generally, the heritability of measured traits in P. elaeagnifolia were higher than those of P. scoparia, especially foreconomically important traits including yield (H2 = 94 and H2 = 54.61, respectively in P. elaeagnifolia and P. scoparia), nut weight (H2 = 97.83 and H2 = 85.39.61, respectively in P. elaeagnifolia and P. scoparia) and oil percentage (H2 = 75.55 and H2 = 61.43, respectively in P. elaeagnifolia and P. scoparia). Stepwise regression analysis revealed that the most influential factors on yield of P. scoparia, were the fruit set, flower diameter and leaf length, whilst for the P. elaeagnifolia, the yield was mostly determined by fruit set and leaf area. The high genetic diversity and heritability of the studied traits, indicates high genetic potential of this germplasm to be utilized in future breeding programs.
