Abstract

The range of variation for ten characters indicated wide differences among thirty genotypes of Ricebean. The phenotypic and genotypic coefficients of variation were high for number of clusters/plant, grain yield/plant, number of pods/plant and 100 seed weight. These characters also exhibited high heritability and high genetic advance as per cent of mean indicating that the characters are under the control of additive genes. The grain yield showed positive and significant correlation with plant height, number of branches/plant, number of clusters/plant, numbers of pods/plant, pod length and 100 seed weight. Path analysis indicated that numbers of pods/plant, 100 grain weight, number of seeds/pod, pod length, plant height and number of branches/plant could be considered as reliable variables for further crop improvement in ricebean.
