| description | Seed size is an important agronomic trait and is applicable to different abilities. Small seeds guarantee the greater use of the pulp, while larger seeds facilitate sowing. However, there is little work on the genetic control of this characteristic in watermelon. The objective of this work was to study the seed size inheritance in watermelon populations by crossing contrasting genotypes, seeking to gain information to provide technical support during the selection of seed size for the development of new watermelon genotypes. The seed lengths of six populations, P1, P2, F1, F2, BC1 and BC2, were measured using the GENES software segregating and nonsegregating generations procedure. This trait is controlled by two genes with incomplete dominance. In addition, depending on the populations studied, inheritance for the characteristic in question may behave differently. Nevertheless, the selection of superior individuals within populations can be performed based on this phenotype, which allows the exploitation of these individuals within breeding programs to develop lines or hybrids. |

El tamaño de las semillas es un rasgo agronómico importante, pudiendo utilizarse para diferentes habilidades. Mientras que las semillas pequeñas garantizan un mayor aprovechamiento de la pulpa, semillas más grandes facilitan la siembra, sin embargo, existen pocos trabajos sobre el control genético de este carácter en la sandía. El objetivo de este trabajo fue estudiar la herencia del tamaño de las semillas en poblaciones de sandía cruzando genotipos contrastantes, buscando proporcionar soporte técnico durante la selección del tamaño de la semilla en el desarrollo de nuevos genotipos de este fruto. Fue medida la longitud de la semilla de seis poblaciones P1, P2, F1, F2, RC1 y RC2 utilizando el procedimiento generaciones segregantes y no segregantes (GENES), por medio del cual fue posible concluir que la herencia del tamaño de semillas en las poblaciones estudiadas es controlada por dos genes con dominancia incompleta. Además, dependiendo de las poblaciones estudiadas la herencia del carácter en cuestión puede comportarse de manera diferente. La selección de individuos superiores dentro de las poblaciones puede ser realizada con base en el fenotipo, lo que posibilita la exploración de estos individuos dentro de los programas de mejoramiento para componer líneas o híbridos.
