STUDIES ON INTERSPECIFIC HYBRID IN PHARBITIS

IV. GENETIC ANALYSIS OF PEROXIDASE ISOZYMES IN P. NIL AND P. PURPUREA HYBRID

Abstract

The interspecific hybrids between Pharbitis nil Choisy and P. purpurea Roth were very low in fertility or completely sterile. F₂ segregations were studied on the cathodal peroxidase isozymes. P. purpurea has 3C isozyme and P. nil has 2C (Africa) and 1C (Tendan and others). The gene Pe^3C specifying 3C isozyme is a codominant allele with Pe^2C and Pe^1C(0).
