Abstract

Although aneuploid individuals are generally less vigorous than their euploid counterparts, they have an important place in genetic research and breeding programs. They can be gainfully employed to localize genes on specific chromosomes, to assign chromosomes in their respective linkage groups, and to assess phenotypic effects of individual chromosomes. Aneuploids have proven useful in locating genes on particular chromosomes in several diploid species, e.g., barley, maize, sorghum, rye, and pearl millet (for references see Khush 1973; Jauhar 1978b). In no other crop plant have aneuploids been as systematically studied as in hexaploid common wheat (Sears 1954). And they have proved immensely useful in elucidating the cytogenetic architecture of this important crop plant. The need for developing aneuploid series in other crop plants cannot be overemphasized. No systematic attempt has been made to synthesize a series of aneuploids in species of the Lolium-Festuca complex.
