Abstract
In Oxalis rosea it is found that some short-styled plants are dominant to non-short (mid- or long-styled plants) whilst others are recessive. Breeding experiments show that the short style form is under the control of two gene pairs (A, a and S, s) with shorts having either of the genotypes aaSS and aaSs. In plants segregating for A, a on an SS background, shorts appear as recessive whilst in plants segregating for S, s on an aa background, shorts appear as dominant. Among non-shorts, mids (MM, Mm) are dominant to long (mm). Genes at the three loci (i) A, a, (ii) S, s and (iii) M, m show independent assortment. These results are compared with previous suggestions of recessive short in O. rosea by von Ubisch (1926) and in O. articulata by Fyfe (1956).
