Little information is available regarding the levels of Meloidogyne incognita race 3 resistance in Acala 1517 cotton cultivars compared with cultivars grown outside the southwestern United States. Levels of M. incognita egg production were compared among commercial Acala cultivars 1517-E2, 1517-SR1, 1517-75, 1517-77BR, and SJ-5, resistant and susceptible standards Auburn 634 and M-8 and breeding lines Acala 5701-W and N6072 grown for 45 days in the greenhouse. The Acala 1517 cultivars all performed similarly, demonstrating moderate nematode resistance. Egg production on the 1517 cultivars was less than on SJ-5 and less than one-fifth that on M-8. Auburn 634 was most resistant, followed by N6072. Total egg production per plant and egg production per gram dry root were not correlated but proved to be reliable indicators of relative resistance to M. incognita.
与美国西南部以外种植的棉花品种相比，关于阿卡拉1517棉花品种对南方根结线虫3号生理小种的抗性水平的信息较少。在温室中种植45天的情况下，比较了商业阿卡拉品种1517-E2、1517-SR1、1517-75、1517-77BR和SJ-5、抗性和感病对照品种奥本634和M-8以及育种系阿卡拉5701-W和N6072上南方根结线虫的产卵量。所有阿卡拉1517品种的表现相似，表现出中等程度的线虫抗性。1517品种上的产卵量低于SJ-5，且不到M-8上产卵量的五分之一。奥本634抗性最强，其次是N6072。单株总产卵量和每克干根产卵量不相关，但被证明是对南方根结线虫相对抗性的可靠指标。
