SALOMON-DIAZ, Jorge L. et al. Use of the Mother-Baby design in the selection of foreign potato cultivars (Solanum tuberosum L.) in Cuba. cultrop [online]. 2020, vol.41, n.3, e05.  Epub Sep 01, 2020. ISSN 0258-5936.

The aim of this assay performed at the National Institute of Agricultural Sciences (INCA) was to use the Mother-Baby methodology in the participatory selection of potato cultivars and to evaluate selection criteria taking account the point of view gender. 74 cultivars were planted in a randomized block design (mother trial) replicated three times in the INCA and in observation plots without replicas in three other production farms. The characterization of the cultivars in the Mother-Baby trial was based on quantitative and qualitative traits, a frequency analysis was carried out for the qualitative ones, and an analysis of variance of a factor and a test of comparison of means, for the quantitative ones by means Duncan´s Test (p≤0.05). The data in the Baby plots were processed through a descriptive statistical analysis, using the IBM SPSS version 21.0 package while the selection criteria carry out for female and male farmers was evaluated through Chi-square test of comparison of proportions. The result showed a great diversity of the quantitative and qualitative traits. From 74 potato cultivars, 41 were selected by the majority of the votes, however, the correspondence of selected cultivars was 15: “Loane”, “Amany”,”Zinared”, “Dirosso”, “Tornado”, “Daifla”, “Touareg”, “Atlas”, “Manitou”, “Arizona”, “Cimega”, “Margarita”, “Rudolph”, “Melanto” y “Faluka” when analyzing their behavior in general in the trials and selections practiced by female and male farmers and plant breeders. Regarding selection criteria carry out for men and women the analysis revealed valuable but different criteria between female and male farmers.On the other hand, valued but different criteria were revealed when considering gender selection.
