Abstract
Haploids were obtained from six tetraploid clones that were selected based upon either high or low specific gravity and low glucose accumulation during storage. Atlantic, Redsen, Red Pontiac, W 710, W 760 and W 842 had frequencies of 20.2, 13.9, 3.8, 6.3, 9.8 and 9.3 haploids/100 fruit, respectively. A total of 702 haploids was produced from: Atlantic (470), Redsen (54), Red Pontiac (2), W 710 (1), W 760 (134) and W 842 (11).
Resumen
Se obtuvieron haploides de seis clones tetraploides que fueron seleccionados en base a una alta o baja gravedad específica, y a una baja acumulación de glucosa durante el almacenamiento. Atlantic, Redsen, Red Pontiac, W 710, W 760 y W 842 tuvieron frecuencias de 20,2, 13,9, 3,8, 6,3, 9,8 y 9,3 de haploides/100 frutos, respectivamente. Se produjo un total de 702 haploides de Atlantic (470), Redsen (54), Red Pontiac (2), W 170 (1), W 760 (134) y W 842(11).
