火参果果实性状评价与种质创制

Fruit character evaluation and germplasm breeding of kiwano germplasm resources

火参果是我国近年发展较快的新型瓜类作物,针对我国火参果种质资源稀少的现状,笔者持续开展了火参果种质资源引进、收集和保存工作,对前期引进的42份火参果种质资源的主要果实性状进行了初步评价,筛选出部分优异种质;另以优异种质TY18与TY19-2为亲本,通过杂交转育方式创制出无刺、黄果类型种质,该种质拥有明显不同于常规种质的果实外形和较高可溶性固形物含量的优质性状,为一种新种质,暂命名为火星20,具有良好的栽培应用价值和育种利用前景。

Kiwano is a new melon crop developed and planted in China in recent years,in view of the scarcity of kiwano germplasm resources in China,we have continuously carried out the introduction,collection and preservation of kiwano germplasm resources.In this paper,the main fruit characteristics of 42 kiwano germplasm resources introduced in the early stage were preliminarily evaluated and some excellent germplasm were screened.In addition,the non prickly and yellow fruit type germplasm was bred by cross between parentsTY18 andTY19-2,the germplasm has the high-quality characteristics of fruit shape and higher soluble solid content,which are significantly different from the conventional germplasm an so it is a new germplasm,temporarily named Huoxing 20,and has good cultural application value and breeding utilization prospect.
