Resistance reaction to Fusarium oxysporum f. sp. batatas (Fusarium wilt) and Meloidogyne incognita (root-knot nematode) of ‘Sodammi’.

Variety Fusarium wilt Root-knot nematode
Disease index (DI, 0~5) Resistance reactionz No. of egg mass per plant Resistance reactiony
Sodammi 1.1 MR 28.3 MR
Jinhongmi 0.5 R 126.3 S
Juhwangmi -x - 0.5 R (Resistant check)
Yulmi - - 139.5 S (Susceptible check)
Singeonmi 0.1 R (Resistant check) 185.7 S
Borami 4.3 S (Susceptible check) 11.0 R

zR (Resistance, DI=0~1.0), MR (Moderate resistance, DI=1.1~2.5), S (Susceptibility, DI=2.6~5.0).

yResistance was determined by number of egg masses per plant. R: ≤10% of a susceptible cultivar (Yulmi), MR: 11~25%, S: >25%.
