Abstract

The use of cytoplasmatic male-sterility in maize seed production contributes to increase economical efficiency and to obtain great genetical seeds. Through this theme one has followed the realization of a comparative study between some hybrids obtained to Turda on C and T cytoplasm their homologues, developed with normal and through the castration of the maternal parents. The researches aimed mainly the phenotypic and genotypic variability of the hybrids, the degree of male-sterility and the capacity of production, in phytotechnic conditions in different densities.
