Resumen
Descripción
A group of potato hybrid combinations were made under greenhouse conditions at the National Institutte of Agricultural Sciences in 1999. The aim of this study was to know the ability of crossing between Solanum genotypes and the association among some characters related to potato berry. Three crossing groups were formed with parental genotypes from Solanum tuberosum (subsp. tuberosum and subsp. andigena) and one wild species. The decapitation method was used for crossing, and characters related to fruit berry were evaluated: seed number, fruit weight, length and width. The main parameters were estimated for the characters related to the fruit, the lineal correlations and path coefficients. A higher variability was observed at seed number per fruit, positive and highly significant correlation coefficients being recorded between fruit weight, length and width as well as between these two last characters. The greatest direct and indirect contribution to berry weight was given by fruit width in the three crossing groups.
