En El Bajío, en siembras de campo, es tolerante a tizón común y resistente a roya, antracnosis, tizón de halo y mosaico común del frijol. Posee los marcadores moleculares SW13, asociado al gen I de resistencia al virus del mosaico común del frijol; Sk14, SI19 y SAD12, asociados a los genes de resistencia a roya Ur-3, Ur-5 y Ur-7, así como SY20, SAS13 y SF10, asociados a los genes de resistencia a antracnosis Co-4, Co-4  2 y Co-10, respectivamente. &#8216;San Luis 22&#8217; se recomienda para temporal en El Bajío y el Altiplano del norte de Guanajuato, Querétaro, San Luis Potosí y Zacatecas. En El Bajío y norte de Guanajuato bajo temporal, San Luis 22 superó en 191 kg ha-1 a Negro Otomí, particularmente en siembras atrasadas de agosto, lo que sugirió mayor plasticidad fenológica.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract &#8216;San Luis 22&#8217; is a medium-sized variety of shiny black beans, it has a prostrate type III indeterminate habit. It has an intermediate maturity cycle, with 95 to 100 days to physiological maturity. Its potential yield under rainfed conditions is 1 450 kg ha-1. In El Bajío, in field plantings, it is tolerant to common blight and resistant to rust, anthracnose, halo blight, and bean common mosaic. It has the following molecular markers: SW13, associated with the I gene of resistance to the bean common mosaic virus; Sk14, SI19 and SAD12, associated with the rust resistance genes Ur-3, Ur-5, and Ur-7; and SY20, SAS13, and SF10, associated with the anthracnose resistance genes Co-4, Co-4  2 , and Co-10, respectively. &#8216;San Luis 22&#8217; is recommended for rainfed conditions in El Bajío and the Altiplano of northern Guanajuato, Querétaro, San Luis Potosí, and Zacatecas. In El Bajío and northern Guanajuato, under rainfed conditions, &#8216;San Luis 22&#8217; exceeded Negro Otomí by 191 kg ha-1, particularly in late sowing in August, which suggested greater phenological plasticity.]]></p></abstract>
