Description Several mutants were induced in the chickpea cultivar JG 315 after seed treatment with ethyl methane sulfonate (EMS). A variegated leaf mutant (Jawahar Gram Mutant 3 or JGM 3) was isolated in the M2 of the 0.4% EMS treatment for 6 h. All leaflets of the variegated leaf mutant showed a large single white lesion on the foliage blade at both sides of the midrib. Each lesion was associated with a constriction at the leaflet margin. Another mutant with apical chlorosis (JGM 6) was isolated in the M2 of the 0.6% EMS treatment for 6 h. In this mutant, the young foliage was always yellow at the growing apex while lower leaves developed chlorophyll and turned light green as they grew older. A foliar spray of 0.5% FeSO4 had no effect on the chlorotic foliage although it corrected soil-borne chlorosis in the accession ICC 4992. This shows that the chlorosis in JGM 6 was not a result of iron deficiency. Both mutations were recessive. The genes controlling the variegated leaf and the apical chlorosis traits are assigned symbols var and ach, respectively. Variegated simple leaf segregants were recovered from the F2 of the cross JGM 3 × ICC 10301 (simple leaf) which have ornamental appearance.
