| Abstract:
Due to diversity in geomorphology, topography and climate, Iran has a unique situation with its richness in genetic diversity in almond genotypes and species. A research has been conducted on naturally grown almond population in Tehran, Qazvin and Zanjan provinces since 2001. Almost the entire almond trees in these regions are of seed origin. In this study, evaluating, and scoring for each trait of almond genotypes, phenological properties and pomological characteristics were carried out based on the IBPGR. In this research, a unique genotype and several late genotypes were selected. Morphology of flowers of G-120 show that its flowers have not petals and stamens, but each flower (swelled flower bud) includes several stigmas (5-9). In a cross-pollination study, it was found that only one stigma pollinated by pollen of the other cultivars and developed into fruit and other stigmas of the flower were sterile. In open pollination and cross-pollination (by hand pollination), fruit set was 0% and 35% respectively. The other morphological, phenological, and pomological characteristics of G-120 (stigmatiode genotype) will be discussed. | |
