RESEARCHES REGARDING THE BEHAVIOR OF SOME CORN HYBRIDS PRODUCED ON A CYTOPLASMIC MALE-STERILITY AND FERTILITY RESTORATION IN COMPARATION WITH THEIR ANALOGUES WITH MALE-FERTILITY
Keyword(s):
Cytoplasm male sterility is used for producing hybrid corn seeds by reason of the economic efficiency and is also advantageous for genetic purity of seeds. Three types of male sterility cytoplasm in maize are used as cms maternal parents to produce hybrids: cms-C, cms-S. cms-T. 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
