Summary or description

"Se evaluaron 18 genotipos de tomate (Lycopersicon esculentum Mill.): 4 progenitores, generaciones de cruzas F1, F2, F3 y retrocruzas (RC1 y RC2). El experimento se realizó en el Campus de la Universidad Autónoma Agraria “Antonio Narro” y en el Laboratorio de Fisiotecnia durante el ciclo Primavera-Verano 2003. Las Variables de Rendimiento Cualitativas a analizar fueron pH, °Brix y Vitamina C. Después del quinto corte se seleccionaron 2 frutos de cada tratamiento a los cuales se les realizaron las pruebas de laboratorio de: pH utilizando un potenciometro Conductronic, °Brix con un refractometro (Atago) y Vitamina C de acuerdo a la metodología de Chechetkin (1984). Se encontró que los genotipos 12 [Retrocruza (Shady Lady x Sunny) x Shady Lady] y el 13 [(Bonita x Sunny) x Sunny] son los mejores, ya que aparte de presentar baja acidez, presentan mayor concentración de sólidos solubles y Vitamina C."

"18 Tomato genotypes (Lycopersicon esculentum Mill.): 4 parents, selfcrosses generations F1, F2, F3 and backcrosses (RC1 y RC2). The experiment was conducted at Universidad Autónoma Agraria “Antonio Narro” campus and in the Plant Physiotechnic Laboratory during the spring-summer season in 2003. The qualitative variables of yield analyzed were pH, °Brix and Vitamin C. After the fifth cut, 2 fruits of each treatment were selected for lab tests. The parameters evaluated were pH, using a conductronic pH meter, °Brix with a refractometer (Atago) and vitamin C according to Chechetkin (1984) methodology. Genotypes 12 [backcross (Shady Lady x Sunny) x Shady Lady] and 13 [(Bonita x Sunny) x Sunny] were the best ones, since aside from presenting low acidity, they both present greater soluble solid concentration and vitamin C."
