Crosses were made between Fanny (highly susceptible to blast) and 11 cultivars differing in blast resistance. Using the pedigree method (PM) segregating generations were evaluated and selected for blast resistance. Via anther culture (AC), doubled-haploids were obtained from F1 plants and from F2...

A method for comparing locations as selection sites based upon their abilities to predict yield and disease reaction over a target region is proposed. The probability of coincidence in selection for a site is defined as the probability for a line selected at the site to be selected at other sites...

The relatively recent developments on statistical methods for the analysis of categorical variables allows parameter estimation and hypothesis testing using linear models on functions of response frequencies. A particular case is the Logit Model, which uses as dependent variable the logit functio...

Gracias a desarrollos relativamente recientes en métodos estadísticos para el análisis de datos categóricos, es posible realizar estimación de parámetros y prueba de hipótesis sobre variables de respuesta categóricas ajustando modelos lineales a funciones de las frecuencias de respuesta. El model...
