Glossy Seedlings in Maize

Abstract

(1) In addition to the glossy seedling located in the linkage group Bn-sl-gl1-ra two new glossy seedlings have been discovered. The three glossies are designated as gl1, gl2 and gl3. (2) Intererosses of gl1, gl2, and gl3 give normal seedlings in F1 and a ratio of 9 normal to 7 glossy in F2. (3) Gl2, appears independent in inheritance of the aleurone factor pairs Ce, Rr and Aa, and of the endosperm factors Wx wx, Sh sh, Su su and Yy. (4) Gl2 is linked with the factor pair for flinty vs. floury endosperm with a recombination percentage of about 30. (5) A summary statement is included which indicates that flinty vs. floury is independent in inheritance with the following factor pairs where the position in the chromosome map is known, namely, Yy, Gl1 gl1, Sl sl, Gg, Ra ra. The flinty-floury factor pair gave independent inheritance also with factor pairs for Minn. No. 13 virescent seedling vs. normal, sorghum tassel vs. normal and brown midrib vs. normal, which have been studied extensively with known linkage groups without finding a dose linkage relation.
