• W2912361270 abstract "El guayabo (Psidium guajava L.) es una de las especies de frutales cultivados mas valiosas de la familia Myrtaceae; sin embargo, se han realizado pocas investigaciones relacionadas con la estimacion de parametros geneticos en poblaciones de esta especie. Es importante para los mejoradores de plantas considerar la heredabilidad del caracter bajo seleccion, los tipos de individuos seleccionados, las asociaciones entre los caracteres y los recursos dis-ponibles para desarrollar una estrategia de seleccion efectiva. El objetivo del presente trabajo fue estimar la heredabilidad en sentido estrecho y las co-rrelaciones geneticas y fenotipicas para caracteres cuantitativos evaluados en tres poblaciones de guayabo. Se realizo un analisis de regresion progenitor-progenie para estimar la heredabilidad en sentido estrecho. Los coeficientes de correlacion genetica fueron estimados con el empleo de analisis de covarianza progenitor-progenie, mientras que las correlaciones fenotipicas fueron calculadas por el coeficiente de correlacion de Pearson. Estos analisis se realizaron en el programa SPSS. Valores relativamente altos de heredabilidad fueron obtenidos para los caracteres altura de la planta y lar-go del fruto. La mayoria de los caracteres mostraron correlaciones geneticas y fenotipicas significativas entre ellos. Los valores de los coeficientes de correlacion genetica y fenotipica fueron diferentes en magnitud, pero tenian el mismo signo en la mayoria de los caracteres. Los resultados indicaron que las correlaciones geneticas fueron superiores a las correlaciones fenotipicas. Estos resultados tienen importancia practica en los procesos de seleccion en el mejoramiento genetico de la especie. Palabras clave: mejoramiento genetico; parametros genetico-estadisticos; familias de medios hermanos; guayaba ABSTRACT Guava (Psidium guajava L.) is one of the most valuable cultivated fruit species of the Myrtaceae family; however only a few researches related to the estimation of genetic parameters has been done in populations of this specie. It is important for the plant breeder to continually consider the heritability of the trait under selection, the type of individuals selected, the associations between traits, and the resources available to develop an effective selection strategy. The objective of this work was estimate the heritability in narrow sense, and the genetic and phenotypic correlations, for quantitative traits evaluated in three guava populations. Parent-offspring regression analysis was used to estimate heritability in narrow sense. Parent-offspring covariance analysis was used to estimate the genetic correlation coefficients whereas phenotypic correlation was calculated by Pearson correlation coefficient. These analyses were made using SPSS program. The relatively high values of heritability were found for plant height and fruit length. Most of the traits showed significance genetic and phenotypic correlations between them. Both coefficients values were different in magnitude but they had the same sign in most of the traits. The results indicated that genetic correlations were superior to phenotypic correlations. These results have practical importance in the genetic breeding selection process of this specie.
