Trypsin inhibitors (TI), tannins, and lectins appear to have a role in preventing chronic diseases in humans. The genetic variability of these traits in common bean needs to be ascertained in order to increase levels through breeding. The variability of TI, tannin, and lectins was determined in five bean cultivars grown at five locations in Mexico. TI and tannins contents in colored beans that belong to the Jalisco race were higher (11.1-11.9 trypsin units inhibited (TUI)/mg and 29.0-38.1 mg catechin equivalent (CE)/g, respectively) than cultivars of the Durango race (7.9-8.3 TUI/mg and 16.8-19.9 CE/mg, respectively). Bayo Victoria, a Durango race cultivar, had three times more lectins than levels reported for soybean. Cultivar influenced TI and tannins contents (p < 0.001), whereas site affected lectins (p < 0.001). An increase in levels of TI and tannins could be enhanced through breeding.
胰蛋白酶抑制剂（TI）、单宁和凝集素似乎在预防人类慢性疾病方面发挥作用。为了通过育种提高这些性状的水平，需要确定菜豆中这些性状的遗传变异性。在墨西哥五个地点种植的五个菜豆品种中测定了TI、单宁和凝集素的变异性。属于哈利斯科品种的有色菜豆中的TI和单宁含量（分别为11.1 - 11.9个抑制胰蛋白酶单位（TUI）/毫克和29.0 - 38.1毫克儿茶素当量（CE）/克）高于杜兰戈品种（分别为7.9 - 8.3 TUI/毫克和16.8 - 19.9 CE/毫克）。杜兰戈品种的巴约·维多利亚的凝集素含量是报道的大豆凝集素含量的三倍。品种影响TI和单宁含量（p < 0.001），而种植地点影响凝集素含量（p < 0.001）。通过育种可以提高TI和单宁的含量。
