The reproductive factor (R = final egg density at 55 days / 5,000, initial egg density) of Meloidogyne chitwoodi race 2 (alfalfa race) on 46 crop cultivars ranged from 0 to 130. The reproductive efficiency of M. chitwoodi race 1 (non-alfalfa race) and M. chitwoodi race 2 was compared on selected crop cultivars. The basic difference between the two races lay in their differential reproduction on Thor alfalfa and Red Cored Chantenay carrot. M. chitwoodi race 2 reproduced on alfalfa but not on carrot. Conversely, alfalfa was a poor host and carrots were suitable for M. chitwoodi race 1. Based on host responses to M. chitwoodi races and M. hapla, a new differential host test was proposed to distinguish the common root-knot nematode species of the Pacific Northwest.
南方根结线虫2号生理小种（苜蓿小种）在46个作物品种上的繁殖系数（R = 55天时的最终卵密度/5000，初始卵密度）范围为0至130。在选定的作物品种上比较了南方根结线虫1号生理小种（非苜蓿小种）和南方根结线虫2号生理小种的繁殖效率。这两个生理小种的基本差异在于它们在雷神苜蓿和红芯尚蒂伊胡萝卜上的繁殖差异。南方根结线虫2号生理小种能在苜蓿上繁殖，但不能在胡萝卜上繁殖。相反，苜蓿是南方根结线虫1号生理小种的不良寄主，而胡萝卜适合其繁殖。基于寄主对南方根结线虫生理小种和北方根结线虫的反应，提出了一种新的鉴别寄主试验，以区分太平洋西北地区常见的根结线虫种类。
