Relation Of Hybridity To The Expression Of Gene Dwarf-1 In Maize Coleoptile Growth, Martin C. Goffinet
Journal of the Minnesota Academy of Science
ABSTRACT - The plants used in this study were two inbred strains of maize and their hybrid. Each strain segregated for the mendelian gene dwarf-1, approximating a ratio of three normal to one dwarf, with l 00 per cent penetrance. The length of each of fifty coleoptiles per strain was determined at planting and after emergence of the seedlings until maturity of that organ. The dwarf seedlings were compared with their normal sibs within each strain to determine the degree of expression of the mutant gene. The growth parameters determined from the measurements were: l) total elongation of coleoptile after …
