Evaluación del rendimiento de tres híbridos (As Rosem 21TO11675, As Rosem 20TO12231, As Rosem 20TO11002) de tomate hortícola (Lycopersicum esculentum) bajo cubierta plástica

Abstract

In the current work, the performance of three hybrids (As Rosem 21TO11675, As Rosem 20TO12231, As Rosem 20TO11002) of horticultural tomato (Lycopersicum esculentum) under plastic cover was evaluated, the improved hybrids were provided by the company SOLOAGRO, a design of completely randomized blocks (D.B.C.A) in three treatments (hybrids) plus a commercial control, performing 4 repetitions. In the investigation, the following variables of survival percentage were evaluated: plant height at 25, 50 and 75 days, stem diameter at 25, 50 and 75 days, number of days to flowering, number of days to fruiting, number of days to harvest, number of fruits, distance between clusters, equatorial diameter of the fruits, polar diameter of the fruits and weight of the fruits. For each of the variables, the ANOVA test was used, homogeneity of variances with a confidence level of 0.95%, Scheffe with a significance level of 0.05. Once the investigation was concluded, it was determined that the hybrids adapted to the climatic conditions of the Huachi Grande sector. From this research, hybrids were obtained that exceeded expectations, having better results than others, the hybrid As Rosem 21TO11675 was the one that best adapted to the agroecological conditions, presenting a higher percentage of survival with 98% of the plants, greater plant height at 50 and 75 days with 0.94 and 1.55 m. greater diameter of the stems at 50 and 75 days with 1.07 and 1.54 cm, presenting fewer days to flowering with 42.70 days, fewer days to fruiting with 57.70 days, greater polar diameter 5 .82cm. consequently, he reported higher performance with 23,300 kg/h. As Rosem 21TO11675 was the best hybrid compared to the other 2 remaining hybrids (As Rosem 20TO12231, As Rosem 20TO11002) and being superior to the Sheila hybrid
