Self-incompatibility is one of the most important difficulties in almond production which reduce fruit set dramatically and makes orchard management difficult. Therefore, breeding almond to produce self-compatible genotypes is very important. In this research identification and screening of 86 almond progenies obtained from selfing Touno after the self-pollination by PCR reaction with specific ...

self-incompatibility is one of the most important difficulties in almond production which reduce fruit set dramatically.therefore, breeding almond to produce self-compatible genotypes is very important. in this research, pollen tube growth was studied in 28 genotypes obtained from crossing between touno (male parent) and shahrood 12 (female parent) after self pollination by fluorescent microsco...

Although pollen tube growth has been an important criterion for self-compatibility evaluation in almond, there is not a clear-cut separation between positive and negative growth of pollen tubes in the different genotypes. The examination of pollen tube growth after selfing almond seedlings has allowed establishing different levels of compatibility, but not a clear-cut separation between self-co...

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...

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...

breeding of almond to attain self compatible cultivars is among the objectives followed in almond breeding. early identification of self-compatible genotypes from self-incompatible ones is very important in saving of time and expenses. there are different methods of either classical or molecular nature to recognize self-compatibility in genotypes. in this study, pcr-based method with specific p...
