May I ask what rootstocks will adapt to desert climate like Saudi Arabia?

Both sour orange & volkameriana should do well for you.

Orange arrived to Spain from north África, about the X century, and the first one was the sour orange. It comes from India and arabs distributed it throughout North Africa until it reached the Iberian Peninsula, and then the rest of Europe.

Here in Saudi Arabia I see different citrus sold in the nursery like Orange, lemon, Lime and Tangerine but I dont know which rootstock they are using. Can I use Orange rootstock to propagate Lemon, Lime and Tangerine?

When you write orange root stock, I am assuming you are referring to Sour orange. Sour Orange is an excellent rootstock with broad soil adaptation. Phytophthora tolerance, and positive fruit quality effects. As tristeza became more widespread, all trees on Sour Orange (except lemons) are likely to be killed. However, if your area does not have Tristeza it is an amazing rootstock.

You can ask in the shops where they sell sweet orange trees which rootstock has the tree and try to buy them, if they don't sell them you can buy the sweet orange and graft whatever you want, or cut it so that the rootstock grows and then you will have material for scions. I have done this on occasion.

Thanks Sanguinho for your helpful tips. I will try to visit the local nursery here if they sell rootstocks. If not I will just plant Sweet orange as a rootstock. I did not find Sour orange, Rough lemon and Cleopatra mandarin in Saudi Arabia.

Sweet Orange can be used as a rootstock for most varieties, but its susceptibility to Phytophthora and citrus nematode often limit the productivity and lifespan of trees. Further, trees on sweet orange have poor drought tolerance and are very susceptible to Phytophthora, so irrigation must be carefully managed. What ever you do I wish you good luck.

If you are going to plant seeds to get the rootstocks, you can try here. www.tradewindsfruit.com/citrus-aurantium-brazilian-sour-orange--seedsThey have more citrus seeds like mandarin cleopatra. Now theybdon't have stock but I think that in May they'll have. But it would be better if you try to get the rootstocks, you will save time and no import problems. If finally you can't get them, maybe I can send you some.

Sweet orange seed is still available for Citrus rootstock use in Australia. I don't think it would be anywhere the most popular choice. It is usually used on new soils for Citrus, i.e. not to replant old orchards. It prefers lighter deep sandy soil, that drains easily, but requires watering. Around here that would be red sandhill soils. Sweet orange seedlings can be sensitive and have more problems when transplanting, than other rootstock types.
What areas and soil types would be used to grow fruit trees in Saudi Arabia.

Riyadh is a desert climate and the soil is sandy and rocky beneath.

aaaahttps://www.sciencedirect.com/science/article/abs/pii/S0304423805000725 Yield, fruit quality, and tree health of ‘Allen Eureka’ lemon on seven rootstocks in Saudi Arabia Abstract Since environmental conditions and cultural practices vary from one area to another, yield, fruit quality, and tree health measurements were conducted over 9 years to evaluate the long-term adaptability and performance to local conditions of ‘Allen Eureka’ lemon (Citrus limon Burm.f.) budded on seven rootstocks in the Najran area of Saudi Arabia. Trees on Citrus macrophylla (CM), Volkamer lemon (VL), and Cleopatra mandarin (Cleo) were the most productive, while trees on Amblycarpa (Amb), rough lemon (RL), Citrus taiwanica (CT), and sour orange (SO)(Citrus aurantium L.) had the lowest yield. Fruit from trees on CM and VL were also the largest in size and had the thickest rind, but were among those that had the lowest juice content and lowest total soluble solids. None of the trees on Cleo, VL, or RL died until the 14th year. However, there was a high mortality rate and severe tree decline on SO, CT, and Amb.
It is interesting that all of these rootstocks are Citrus varieties, or species in the old classification, and no modern trifoliate hybrids such as Citranges or Citrumelos were trialled. Other possible rootstock candidates could be Cuban Shaddock or Palestine Sweet Lime, PSW was used in the past in the region, but possibly less so now
