Study of Spanish chestnut cultivais using SSR markers

The chestnut crop in Spain is spread from the northern Iberian Peninsula to the Canary Islands. During a 15-year period we have located 210 cultivar denominations of which 152 can be classified by morphology and isoenzymes; 58 of which are important and 94 very local ones. In 2004, we begun to study...

Description
Summary:The chestnut crop in Spain is spread from the northern Iberian Peninsula to the Canary Islands. During a 15-year period we have located 210 cultivar denominations of which 152 can be classified by morphology and isoenzymes; 58 of which are important and 94 very local ones. In 2004, we begun to study ten microsatellites to determine the relationships between them, including those found in the Canary Islands. Microsatellites confirmed the high variability found in Spain. A total of 73 alieles were found and heterozygosity was double that with isoenzymes. As a whole, the population of cultivars were in Hardy-Weinberg equilibrium. While these results are preliminary, cultivars from northern Spain can be said to be closely related, due to common cultivars such as 'Parede', and cultivars from Tenerife could have their origin in eastern Andalucía.
