Chickpea (Cicer arietinum) has a racemose type of inflorescence and at each axis of the raceme, usually one or two and rarely three flowers are borne. Plants producing 3 to 9 flowers, arranged in a cymose inflorescence, at many axis of the raceme, were identified in F2 of an interspecific cross ICC 5783 (C. arietinum) × ICCW 9 (C. reticulatum) in which both the parents involved were single-flowered. A spontaneous mutation in one of the two parents or in the F1 was suspected. However, the possibility for establishment of a rare recombination of two interacting recessive genes could not be ruled out. The number of pods set varied from 0 to 5 in each cyme. Inheritance studies indicated that a single recessive gene, designated cym, is responsible for cymose inflorescence. The allelic relationship of cym with sfl, a gene for double-flowered trait, was studied from a cross involving multiflowered plants and the double-flowered line ICC 4929. The cym gene was not allelic to sfl, suggesting that two loci control the number of flowers per peduncle in chickpea. The cym locus segregated independently of the locus sfl, ifc (inhibitor of flower colour) and blv (bronze leave)
