Morphological Variability of Eustoma Hybrids Obtained From Interspecific Crosses Between Eustoma Grandiflorum X Eustoma Exaltatum

Abstract

The morphological characteristics of hybrid lines obtained from interspecific crosses between Eustoma grandiflorum and Eustoma exaltatum were analyzed based on the descriptors reported by UPOV for Eustoma grandiflorum. In the principal component analysis, a variation of 73.70% was obtained within four main components. The hybrids of the genus Eustoma were grown in weather conditions with temperature up to 44.5°C in Yucatan Mexico. The 1512063, 1512096, 1512098, and 1512100 hybrids showed a good development plant height, number of nodal segments, flower number and flower size, so that these hybrids could be cultivated tropical regions for commercial purposes.
