| Abstract: | Sugar Baby susceptible to Fusarium oxysporum f. sp. niveum was crossed with high resistant male parents D3 - 1 and D3 - 2, respectively. F1 hybrids showed high resistance. The segregation ratios of resistance to susceptibility of F2 and of BC1 hybrid population from Sugar Baby tallied with 3: 1 and 1: 1, respectively. The results indicated that the resistance to Fusarium wilt was a kind of dominant inheritance controlled by mono- gene or mono- segment DNA. Furthermore, 5 hybrid combinations with fine character were bred. Among them, 3 were high resistant to Fusarium wilt,and 2 were medium res stant |
