Screening Selected Solanum Plants as Potential Rootstocks for the Management of Root-Knot Nematodes (Meloidogyne incognita)

Table 2

Response of four rootstocks to four RKN inoculum levels on gall scores, egg count per gram of root, and reproductive factors 6 and 12 weeks after inoculation in pot experiments.

Rootstocks	Initial inoculum	Mean gall score (1–10)		Nematode count per 200 cc of soil (Pf)		Egg count per gram of root		Reproductive factor (Pi/Pf)		Reaction
