摘要
Seed transmission of potato spindle tuber virus (PSTV) has special significance for potato breeding programs. Transmission of PSTV has been reported to occur via true seed. Test families in the Frito-Lay breeding program were obtained from self- and cross-pollinations to determine the incidence of infected seedlings from healthy and diseased parents. Diseased seedlings from PSTV-infected Katahdin selfed were scored by visual and tomato index procedures as 100% and 87% infected, respectively. A similar result was obtained among seedlings from the cross of PSTV-infected Sebago x PSTV-infected Katahdin. Symptoms of PSTV infection were not detected by either method among seedlings from healthy Katahdin, selfed. The Frito-Lay, Inc., potato breeding program employs a number of phyto-sanitary procedures to exclude or reduce the possibility of PSTV contamination and spread. © 1969 Springer.
