The standards and parameter* adopted by the International Mehidagyiw Project were followed. All tcsied eultivaii were found to be susceptible and good hosts to M. javanica. Value*, of gall index GI (0*5} ranged from 7 3 for cv. Plant* <o 5.0 fOT cvs. Agria. Mondial arid Morene Reproduction factor RF ranged fmm 4.] iorcv. Le*ltatn1M.?forcv. Mondial. Although all cultivars were designated susceptible, they differed (P ^ 0.05) with respect to GI.
