西瓜砧木,长期沿用葫芦品种,不仅失去了抗性,并且降低了西瓜品质。进入80年代,开始利用南瓜作砧木,为西瓜砧木的更新换代开辟了新路。我们经过多年的选育,共选出22个南瓜品种作为杂交亲本,并培育出12个杂交种,经过试验示范多次筛选,选用了5个品种在本省和北京大兴、安徽砀山、河南开封等全国各地进行了推广。其中南杂2号和南杂6号备受欢迎。在本省西瓜生产大县昌乐和昌邑、微山推广鉴定:这两个杂交种与西瓜不同品种的嫁接亲和性好,成活率95%以上;共生亲和力强,生育期160～210天,抗低温,耐高温,抗枯萎病效果 Watermelon rootstock, long-term use gourd varieties, not only lost their resistance, and reduce the quality of watermelon. Into the 80’s, began to use pumpkins as rootstocks, watermelon rootstocks opened up a new road to replacement. After years of breeding, we selected 22 pumpkin varieties as hybrid parents and bred 12 hybrids. After several trials and demonstrations, we selected 5 varieties in our province and Beijing Daxing, Anhui Dangshan and Henan Kaifeng etc. Across the country to promote. Among them, Nansha 2 and Nansha 6 are very popular. In the province, watermelon production Changle and Changyi, Weishan promotion identification: the two hybrids and watermelon grafted varieties of good affinity, survival rate of 95% or more; symbiotic affinity, the growth period of 160 to 210 days, Anti-low temperature, high temperature, Fusarium wilt effect
