The almond, Prunus dulcis Miller which belongs to Rosaceae family, is one of the most important commercial and oldest cultivated tree nut crops. Almonds are classified as a ‘nut’ in which the edible seed is the commercial product. Therefore, pollination and fertilization are necessary in almond. The characteristic of cultivated almond to express gametophytic self- incompatibility discourages se...

grapes are among the world most planted horticultural crops. since the last century, attempts have been made to improve the quality of grapes in the world. meanwhile, the necessity of having knowledge about the history of progenies families led to the link between genealogy and breeding. considering some previous mislabeling, in order to find out the accuracy of the controlled crosses as well a...

five improved along with three local rice varieties were crossed in a line× tester method in 2001. fifteen f1 hybrids and eight parental genotypes were planted in a randomized complete block design with 3 replications at rice research institute of iran, rasht, in 2002. the main objective of the research was to estimate the general and specific combining ability and gene action for 10 agrnomic a...

almond is one of the most important species of genus prunus. most almond cultivars and genotypes are self-incompatible and some of others are cross-incompatible. in this study compatibility and frequency pollen tube penetrate in the ovary were performed in three groups. the first group included the genotype a9.7 as female parent and tuono with genotypes a230, a10.11, a8.39 as male parents, the ...

The finding of new self-compatible cultivars in local population is a breeder’s objective in order to increase the sources of self-compatibility for the almond (Prunus amygdalus Batsch) breeding programmes. ‘AS-1’, a local Spanish selection, was considered to be self-compatible according to its self pollen tube growth and was incorporated in the almond breeding programme of Zaragoza as a source...
