Abstract
Fifty clones selected from crosses between Phureja and Tuberosum haploids and 24 Tuberosum haploids were used to produce two Design I trials, and one Design II trial. Tests were conducted for 2 years at one location, and estimates were obtained for quantitative genetic variance for tuber number and weight. Estimates of genetic variance for tuber number were large, with approximately equal additive and dominance components. Additive genetic variance was the larger component for tuber weight for two of the three estimates. More results from other populations are needed to establish the relative importance of the quantitative genetic components in potatoes.
Resumen
Cincuenta clones seleccionados de cruzas entre Phureja y haploides Tuberosum y 24 haploides Tuberosum fueron usados para establecer dos ensayos del Diseño I, y un ensayo del Diseño II. Las pruebas fueron conducidas por dos años en una localidad y las estimaciones de la varianza genética cuantitativa fueron obtenidas para número y peso de tubérculos. Las estimaciones de la varianza genética para número de tubérculos fueron grandes con los componentes de aditividad y dominancia aproximadamente iguales. La varianza genética aditiva para peso de tubérculos fué el componente mas grande en dos de las tres estimaciones. Más resultados de otras poblaciones se necesitan para establecer la importancia relativa de los componentes de la varianza genética cuantitativa en papas.
