ANALISIS DEL RENDIMIENTO DE GRANO Y SUS COMPONENTES EN CEREALES SINTETICOS (TRICEPIROS Y TRITICALES).

The yield components of tricepiro and triticale experimental lines, with aptitude for grain and forage production, were analyzed in this work as an indirect approach to improve grain production. Partitioning of single correlations in direct and indirect effects provides information on the functional relationship between components of different hierarchy and the end product. The thousand grain weight showed a highly significant direct influence on grain yield. The number of grain per ear had also a significant effect but was a less explanatory variable. The use of these two variables together would help plant breeders to select genotypes with better grain yield. [ABSTRACT FROM AUTHOR]
