Abstract

In interspecific crosses in Solanum using certain introductions of Solanum verrucosum as female partners, a certain type of male sterility is observed referred to as tetrad sterility. This type is characterized by clumping of the sterile pollen grains in tetrads. In the same F1 hybrids, the pollen grains show a three-lobed appearance. Both tetrad sterility and lobed appearance of pollen grains are inherited through the interaction of dominant genes (Tr and Ld respectively) with the corresponding sensitive [Trs] and [Lds] plasmons, both plasmons occurring in S. verrucosum. The study of one of the interspecific hybrids led to the detection of duplicate linkage groups including the loci Tr and Ld with a recombination percentage for these loci of 13.7%. The possibility of a basic chromosome number less than 12 in Solanum is discussed in connexion with the occurrence of duplicate loci.
