Research on male flower structure of chestnut (Castanea sativa Mill.) genotypes identified by selection

The study aims to analyzethe structure of male flowers of chestnut (Castanea sativa Mill.)genotypes selected as a result of selection study in district of Aydın Province Nazilli. The catkin lenght, the number of male flower cluster according to tepal male organs, height, number of flower cluster on the catkin, the male organ in the number of flowers, anters on features such as size measurements of male flowers selected among the stamen during the blooming period in 2012 were measured and the related study was carried out under a microscope. This study shows that genotypes N-2-5, N-3-4 and N-23-1 are defined as no-stamen genotypeas they do not form any anthers and owing to this fact they do not have the ability of duster since they are sterile The Microscopic study showed that the genotype N-7-3 has a mesostaminate and the genotype N-20-2 has a longstaminate.
