โœฆ 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 .
