Abstract

Kilen and Hartwig (1975) have described a short internode character found in PI 227.224 which causes a zigzag stem appearance. They indicated that the short internode character was probably determined by a single recessive gene pair based on classification of the presence or absence of the zigzag stem appearance. In the F2 generations of the crosses, PI 227.224 x 'Coker 338' and PI 227.224 x 'Davis,' we observed two different ratios.
