Genetic analysis of multiloculed pod character in sesame

Abstract

Genetic analysis of he multiloculed condition in sesame was undertaken. Four multiloculed types isolated from a varietal collection and the four loculed type (Kayamkulam-1) were crossed in all passible combinations. The pod type in the hybrids was compared with that of the parents and conclusions drawn. The multiloculed condition was recessive to the four loculed condition. Estimation of the number of genes responsible for this character revealed the operation of two independent recessive genes symbolised as i ' and 'I/. Either of these in hoTiozygous condition produced multilocular expression. Presence of these two genes together in a genotype in the double recessive condition can produce a better expression of this character.
