“…The results obtained in our study, are in agreement with the results observed by El-Shaieny [16] where they found an average of hundred seed weight of about 11 grams for one of the varieties under analysis. However, those results are low when compared to the results obtained by El-Shaieny [16] while studying the Stability analysis of components characters in cowpea (Vigna unguiculata (L.) Walp), where the results obtained were based on an average of 18 grams.…”

“…Estos resultados señalan que al menos entre dos ambientes o entre dos genotipos se registraron diferencias en las características evaluadas. La presencia de interacción significativa refleja las diferentes sensibilidades de los genotipos en los ambientes evaluados, lo que limita la identificación de cultivares superiores para todo el Caribe húmedo con diferentes condiciones ambien-tales, circunstancia que concuerda con [9,11,12,13 en Montería 2013B (Cuadro 3), lo que puede obedecer a la cantidad y distribución de la precipitación y la fertilidad de los suelos [3].…”

“…En lo concerniente a genotipos (Cuadro 4), el número de semillas por vainas varió entre 11,33 (L-047) a 14,16 (L-014) con una media de 12,24, valor superior en un grano al reportado por [11] y menor en dos granos al encontrado por [3]; el peso de 100 semillas fluctuó entre 14,48 g (L-034) a 20,44 g (L-042) con una media de 17,44 g que es superior a la reportada por [3,11]; en tanto que el rendimiento de granos varió de 554 kg ha-1 (L-020) a 1104 kg ha-1 (L-042) con una media de 920 kg. ha-1, superior al reportado por [3,11,16]; que acusaron valores medios de 794 y 706 kg ha -1 , ello demuestra que existe una estabilidad agronómica en la cual los genotipos responden efectivamente al potencial productivo ofrecido por los ambientes.…”

“…The significant interaction between system and genotype effects indicated that genotype responded differently to changes in system production. High proportion of variation on yield and yield components were found for the genotype effect, therefore more testing sites are needed or the environments in locations need to be controlled (Gurung et al, 2012;El-Shaieny et al, 2015). Many study researchers and many plants reported that yield and yield components content are affected by genetic and environment conditions.…”
