Inheritance of moderate pod-reticulation in groundnut (Arachis hypogaea L.)

Abstract

Pod characteristics like reticulation, constriction, beak, pod size etc. are important traits associated with identification of varieites in groundnut. The reports in literature show that prominent reticulation of the pods was reported to be dominant to absence of pod reticulation [1-4]. Badami [1] hypothesized at least four factors for deep reticulation whereas Manoharan and Ramalingam [4] reported two factors for the same. Using three crosses involving parents with pods with moderate reticulation and with smooth pod, Radhakrishnan et al. (personal communication) proposed a digenic inhibitory gene action system for pod reticulation.
