Líneas Mantenedoras (Líneas B) Y Restauradoras (Líneas R) De Sorgo Granífero Adaptadas a Los Valles Altos Centrales De México

Abstract: Los Valles Altos Centrales de México (cerca de 1.5 millones de hectáreas) comprenden áreas agrícolas con altitudes de 1800 a 2300 m. En esta región no existen siembras comerciales de sorgo (Sorghum bicolor L. Moench), pues las variedades e híbridos disponibles no producen grano ya que las bajas temperaturas (entre 5 y 12 ºC) que prevalecen antes de la floración provocan que el polen sea estéril (Livera y Carballo, 1985). Estas temperaturas se presentan incluso en regiones donde se cultiva comercialmente sorgo,… Show more

“…LER 2 is also an R line, but this was selected by the Colegio de Posgraduados (high elevation, close to Mexico City), with adaptation to cool weathers. LEB 1, LEB 2, and LEB 3 (self-pollinated) were also selected by the Colegio de Posgraduados [48]. The LEB are insensible to photoperiod; their limbs show no anthocyanin pigmentation; tannins in grain are scarce or absent; and they exhibit floury predominant endosperm (75%), and light brownish glumes.…”

“…The LEB are insensible to photoperiod; their limbs show no anthocyanin pigmentation; tannins in grain are scarce or absent; and they exhibit floury predominant endosperm (75%), and light brownish glumes. The color of the grain is 'A'/'B', creamy and opaque [48]. It was of interest testing the lines selected in the Colegio de Posgraduados under highly contracting weather conditions of northeast Mexico.…”

“…Williams et al (2006) informaron como posibles causas, el desconocimiento de la tecnología de producción de semillas, y el manejo de plagas y enfermedades. Aunque se han generado líneas e híbridos nacionales para distintas regiones y condiciones (Flores-Naveda et al, 2013;Galicia-Juárez et al, 2020;Mendoza-Onofre et al, 2017;Rodríguez et al, 1998) la producción de semilla hibrida de sorgo se limita a ciertas regiones de los estados de Tamaulipas, Sinaloa y Guanajuato, y a genotipos liberados por INIFAP (Williams et al, 2006).…”
