โฆ Synopsis
Results obtained from 9 weeks of observation of inoculated plants from the tomato cross Plant Introduction (P .1 .) # 235673 x Fireball suggest that in this cross genetic control of inheritance of resistance to Tobacco Mosaic Virus (TMV) to be multigenic .
Virus assay made from inoculated plants of parents and progenies suggested that resistance depended upon the suppression of virus multiplication . For the susceptible parent, Fireball symptoms appeared 14 days after inoculation while the resistant parent ranged from 35 to 49 days . Virus concentration for Fireball was much higher and remained constant during the period while for P .1. # 235673, it was lower and less concentration was required for symptoms to appear as the plants grew older .

Seedlings of two tomato varieties, one susceptible and the other resistant to TMV, were inoculated at the first true leaf stage with a mixed inoculum of TMV and PVX. PVX was added to induce an active and uniform reaction. The seedlings were then grown in flats in the greenhouse, and plants were harv
In comparisons made under typical summer conditions in the field at Davis, California, the foliage of the anthocyanin-deficient mutant af proved to be much more susceptible to attack by Epitrix hirtipennis (MELSHEIMER) than that of the isogenic normal line, normal cultivars, or any other tested muta
