18 The effect of the pollination time and of the pollen origin was studied in three self-compatible 19 and late-blooming almond genotypes in order to evaluate their effect on fruit set and yield. 20 The full self-compatibility of the three genotypes was clearly assessed as fruit sets after self21 pollination were similar to those obtained after cross-pollination with pollen from two 22 differen...

Different experiments have showed that interruption in pollination is an important problem in most almond orchards.Asmost of the almond cultivars are self-incompatible,pollination cannot be performed desirably and as a result a failure in almond yield is occurred.Thus under this circumstance,determination of selective cultivars compatibility and choosing appropriate pollinizers are so important...

Self-incompatibility has been studied by using controlled pollination, pollen tube growth and PCR methods in the Iranian almond ‘Mamaei.’. Pollen tube growth and fruit set following self and cross-pollination treatments were evaluated. The percentage of initial and final fruit set was determined for each treatment at 30 and 60 days after controlled pollination. Pollen germination and pollen ...

Prunus (Rosaceae) includes many commercially important fruit crop species that exhibit self-incompatibility (SI), including sweet cherry (P. avium L.), Japanese apricot mume Sieb. et Zucc.), plum salicina Lindl.), armeniaca and almond dulcis [Mill.] D. A. Webb.). These S-ribonuclease-based gametophytic SI, which prevents self-pollen tube growth in the pistil. The successful production of self-f...

Almond is a highly heterozygous species with a high number of S-alleles controlling its gametophytic self-incompatibility system (GSI). In this work we have analysed Spanish local almond cultivars for S-RNase allele diversity. By cloning and sequencing five new S-RNase alleles were identified: S31 (804 bp) in 'Pou de Felanitx' and 'Totsol', S32 (855 bp) in 'Taiatona', S33 (1165 bp) in 'Pou d'Es...
