| description | Introgression of the recessive sp gene, responsible of determinate growth, was carried out from IPA 4 Brazilian tomato to UNAPAL-Maravilla Colombian “chonto” tomato to modify the architecture of the plant and contribute to the reduction of production costs. In the F2 generation of the fourth backcrossing, the selection of plants with a height of less than 150 cm, a fruit weight of more than 90 g and an oblate fruit shape was carried out. After the selection process, six lines of tomato “chonto” with a determinate growth habit and characteristics of this type of tomato were evaluated. The D5 and D6 lines with determinate growth were selected, with a plant height of 109.30 and 114.40 cm, harvest days of 87.75 and 87.25, and yield per plant of 4,116.6 and 4,029.7 g, respectively. |

Se efectuó la introgresión del gen recesivo sp responsable del hábito de crecimiento determinado, presente en el tomate brasilero IPA 4, al tomate “chonto” colombiano UNAPAL-Maravilla, para modificar la arquitectura de la planta y contribuir a la reducción de costos de producción. En la generación F2 del retrocruzamiento cuatro (F2RC4) se llevó a cabo la selección de plantas que presentaban alturas menores a 150 cm, peso de fruto mayor a 90 g y formato de fruto ovalado. Se obtuvieron y evaluaron seis líneas de tomate “chonto” con hábito de crecimiento determinado y características propias de este cultivar. Se seleccionaron las líneas D5 y D6 porque presentaban crecimiento determinado con altura de planta de 109,30 y 114,40 cm, precocidad a cosecha de 87,70 y 87,20 días después del trasplante y producción de 4.116,60 y 4.029,70 g por planta, respectivamente.
