Abstract he proseZ2.t irtrostigatj.on il2olucled the stady of inhe)i— janoe of fow quztUtat3.ve characters and eight çuantitative in crosses between snake cuctuibor and sweet melon. The :zesults are stmmarized in the fob wing: 1. Monoecious sex type of snake cucumber was dominant rer and.romonoecious type of sweet melon and appeared to be gover— nod by one pair of genes, 2. Resistance to powdery mildew of sweet melon parent was dominmit over susceptibiity of snake cucumber and appeared to be governed by two uplioate genes. At least one dominant allele of resjsta±ice should be present to induce resistance. 3. White seed coat colour of snake cucumber was dsminant over ye1lw seed. coat colour of sweet melon and appeared to b governed by one pair of genes. 4.. Orange flesh colour of snake cucumber was dominant over white flesh of sweet melon. This character behaved as controlled by one pair of genes with modifiers. 5. Ovary diameter was inherited in a quantitative manner parf,il ô.omincuiae o1he Iende’ QVaZr. Mizg tmber of genes con Uing t14a charoier was estiu&ted to be three 6.
