| Descripción: | The objective of this study was to estimate the General and Specific Combining Ability (GCA andSCA) values of yield in pepper. The IV fixed model of Griffing was used to define the best breeding method.Crosses were conducted in a green house at the Universidad Autónoma Agraria Antonio Na rro (UAAAN ), Saltillo, Coahuila. The evaluation was realized in the ExperimentalStation of Huastecas, National Institute of Research Forestry Agricultural and Livestock (INI FAP), Villa Cuauhtémoc,Tamaulipas, in the autumn-winter cycle of 2008. Six types of pepper were utilized, three belonging to jalape ño type (4,6 y 118), one Yellow wax type (8), one broad (“ancho”) type(16) and a brown (“mulato”) type. Six direct crosses were evaluated for days to flowering and days to first harvest, fruityie ld per plant, fruit diameter, and fruit length, and average weight per fruit and yield per hectare. The best genotypes were 6 and 16, and the best crosses for their specific combining ability were 6x16, 4x6. Cross 16x118 showed higher yield. |
