| Summary: | Sebanyak 40 isolat Fusarium oxysporum f. sp. cubense (FOC) dari
Indonesia, Sumatra, dan Semenanjung Malaysia yang dipencil dan pelbagai
variety pisang utama di Asia tenggara telah dikenalpasti dari segi morfologi, ras
dan keserasian vegetatifnya. Keputusan analisis keserasian vegetatif (VCG)
menunjukkan kehadiran 'clonal lineages' di Semenanjung Malaysia. Sebanyak
12 kelompok keserasian vegetatif telah dikenalpasti. Lima kelompok adalah
sarna dengan VCG 0121, VCG 0124, VCG 01213, VCG 01216 dan VCG
01213/01216. Tujuh kelompok yang lain tidak dapat dikategorikan
menggunakan sistem VCG yang sedia ada.
Forty isolates of Fusarium oxysporum f. sp cubense (Foc) located in Indonesia
(Sumatra) and Peninsular Malaysia were isolated from a diverse banana
variety host range which included all significant South East Asian cultivars were
characterized by morphology, race and vegetative compatibility (VCG). There
appeared no direct pattern of association between race, VCG and
morphological characteristics. VCG analysis indicated that there were several
distinct clonal lineages present in Peninsular Malaysia. Twelve compatibility
groups were identified, five of which were previously characterized as VCG
0121, VCG 0124, VCG 01213, VCG 01216 and VCG 01213/01216. |
