Galling and reproduction rates of Meloidogyne floridensis isolate MfGnv14 and M. arenaria isolates Ma1 and Ma2 applied at 20,000 eggs/plant on 1-year old true-to-variety peach cv. Flordaguard after 5 month’s growth under greenhouse conditions.

Nematode isolate	GIa	EMIa	EGFRb	RFb
MfGnv14	3.9	3.8	58	0.46
Ma1	3.1	3.1	65	0.40
Ma2	3.0	3.1	60	0.39
P-value	0.375 ns	0.547 ns	0.5414 ns	0.765 ns

Notes: ^aGalling (GI) and egg mass (EMI) indices were based on a 0 to 5 scale where 0 = no galls or egg masses, 1 = 1-2, 2 = 3-10, 3 = 11-30, 4 = 31-100, 5 = >100 galls or egg masses per plant (Taylor and Sasser, 1978). Data were subjected to log₁₀ (x + 1) transformation before analysis of variance. Data are non-transformed means of eight replicates. ^bEGFR = Eggs per gram of fresh root weight. Reproduction factor (RF) = ratio of nematode eggs at 5 months after inoculation to initial inoculum concentration of 20,000 eggs (Sasser et al., 1984). EGFR and RF data were subjected to arcsine and fourth-root transformation, respectively, before analysis of variance. Data are non-transformed means of eight replicates. Means in the same column followed by the same letter are not different (P < 0.05) based on Tukey’s honest-significant difference test. ns = No statistically significant differences among means.
