Among the major cucurbit vegetables, melon (Cucumis melo) has one of the greatest polymorphic fruit types and botanical varieties. Some melon fruits have excellent aroma, variety of flesh colors, deeper flavor, and more juice compared to other cucurbits. Despite numerous available melon cultivars, some of them are exceedingly susceptible to several diseases. The genetic background carrying the genes for tolerance and/or resistance for those diseases is found in wild melon landraces. Unfortunately, the commercial melon varieties are not able to produce viable hybrids when crossed with their wild melon counterparts. Plant tissue culture techniques are needed to surpass those genetic barriers. In vitro melon embryo rescue has played a main role to obtain viable hybrids originated from commercial versus wild melon crosses. In this chapter, an efficient and simple embryo rescue melon protocol is thoroughly described.
在主要的葫芦科蔬菜中,甜瓜(黄瓜属甜瓜种)具有最多样化的果实类型和植物变种之一。与其他葫芦科植物相比,一些甜瓜果实具有出色的香气、多样的果肉颜色、更浓郁的风味和更多的汁液。尽管有大量可用的甜瓜品种,但其中一些对几种病害极为敏感。野生甜瓜地方品种中存在携带这些病害耐受性和/或抗性基因的遗传背景。不幸的是,商业甜瓜品种与野生甜瓜杂交时无法产生可育杂种。需要植物组织培养技术来突破这些遗传障碍。甜瓜胚挽救在体外已在获得源自商业甜瓜与野生甜瓜杂交的可育杂种方面发挥了主要作用。在本章中,将全面描述一种高效且简单的甜瓜胚挽救方案。
