بررسی و شناسایی بهترین ژنوتیپ های گرده دهنده پسته در منطقه فیض آباد

This pattern was performed in order to recognition and introducing of the best pistachio pollinizer genotypes in fiezabad region within a period 2 years in area over 5000 hectar. The result showed that flowering characters are very important, for the selection of the pollinizer genotypes and according to all phenotypes was classified to three groupes: 1-early blooming ,2-moderate blooming and 3- late blooming. There was a direct relationhip between the time of flowering and environment temperature and there was 8-10 days difference in time flowering in difference years. The length of period flowering was from 4-25 farvardin (22 days), that KA-5 genotype with 13 days and KH-1 genotype with 5 days ,have the most and the least , respectively.The number of flower bud on per branch was different from bud three in TA-1 genotype to bud eight in KA-5 genotype.The amount of pollen grain in per inflorescence among genotypes was different from 130 m.g in AS-1 genotype to750 m.g in FA-1 genotype. The results showed that 14 genotypes are the best pollinizer genotypes for female cultivars in fiezabad region, khorasan province.
