Marginal Chlorosis, A Seed-Borne Virus of Arachis Hypogaea Variety " Schwarz 21 ’’ in New Guinea.

Abstract

Observations on the symptoms, effect on yield, and experimental data are given on the seed-borne virus disease of Arachis hypogaea variety " Schivarz 21 ” in New Guinea. Attempts at mechanical, soil and insect transmission were unsuccessful, but the virus was transmitted through cleft grafts from Schwarz 21 to Red Spanish, White Spanish, Schwarz 21, Virginia Bunch and Natal Common. The virus causes a severe stunting of the affected plants, with marginal chlorosis and crinkle of the leaves.
