Genetic diversity of local red rice cultivars collections of Yogyakarta AIAT, Indonesia based on morphological character

Abstract

Identification of local red rice was important to study for genetic diversity. The objective of the study was to identify the morphological characteristics to estime the genetic diversity and heritability in the broad sense of 11 local red rice cultivars. The quantitative data (plant height, leaf length, leaf width, number of productive tillers, panicle length, 1,000-grain weight and number of grain per panicle) were measured by their CVg values for determining their relationships and heritability. The results can be used for parent selection in a breeding program. Results showed that the number of productive tillers, leaf length and the number of grain content per panicle for 11 local red rice from Yogyakarta were efficient and effective characters in selection because the characters have wide of the coefficient of variation genetics and high heritability value.
