Identification of stable morphological and anatomical characters of sorghum [Sorghum bicolor (L.) Moench] stalk

Abstract

Many morphological and anatomical characters of sorghum-stalk are associated with lodging and plants ability to withstand invasion of stalk-rot pathogens [1]. Morphological characters namely, plant height [2] and stalk diameter [3] and anatomical characters namely, number of vascular bundle and positioning of vascular bundle in stalk play significant role in determining stalk strwgth, lodging resistance [4] and charcoal rot intensity [5] in sorghum. It is, therefore, important to know the stability in performance of rabi sorghum genotypes for the above characters. The present study deals with the stability analyses of morphological and anatomical characters of sorghum-stalk for eight genotypes of rabi sorghum grown under three environments.
