Abstract

A visual rating system for nodulation was developed, based on the use of reference photographs representing the extent of nodulation on a 1-5 scale. The roots of 10 plants from each of 18 genotypes from Hisar and 16 from ICRISAT were washed and their nodulation status was compared by visual rating, nodule number and nodule mass. The correlation between visual rating and nodule number was 0.79 at both locations, and between visual rating and nodule mass it was 0.84 at ICRISAT and 0.85 in Hisar. Although the reference photographs were taken from 45-day-old chickpea plants, depending on the soil conditions they may be used for estimation of nodulation of 40-110-day-old plants.
