摘要: espanolEl melon (Cucumis melo L.) pertenece a la familia de las Cucurbitaceas, posee una amplia diversidad morfologica y es especies mas importantes economicamente en el mundo. Ademas ser excelente fuente nutrientes tales como carbohidratos, acidos organicos, minerales vitaminas, posible cultivarlo durante gran parte del ano. Por otro lado, crece regiones tanto tropicales subtropicales; dando un amplio margen los paises productores para mantener abastecimiento producto todo Sin embargo, se enfrentan con problemas ocasionados principalmente por insectos, bacterias, virus hongos. Estrategias biotecnologicas transformacion genetica plantas pueden mejorar tolerancia estreses bioticos que afectan produccion, traves insercion genes ayudan combatir estos problemas. Se han realizado esfuerzos crear transgenicas partir muchas variedades utilizando embriones somaticos, semillas, cotiledones, tubo polinico, hojas yemas o nudos cotiledonarios mediante Agrobacterium tumefaciens, A. rhizogenes, biobalistica e inoculacion directa, calidad postcosecha fruto, conferir factores abioticos salinidad estres hidrico, asi resistencia fitopatogenos. Como resultado, creado varias expresando diferentes caracteristicas fenotipicas deseables. En este trabajo compila analiza informacion disponible sobre mejoramiento genetico melon, haciendo enfasis desarrollo estrategias utilizadas manipulacion objetivo introducir interes agronomico. EnglishThe belongs to the Cucurbitaceae family, shows large morphological variation and it is one of most important species from economic point view. Besides being rich source nutrients such as carbohydrates, organic acids, minerals vitamins, can be grown throughout year. It grows in tropical subtropical regions, giving wide margin producing countries maintain an adequate supply all However, producers have deal with yield reductions due attack insects, fungi. Biotechnological strategies genetic transformation improve tolerance this crop biotic stresses by insertion that help struggle against these problems. Efforts been carried out create transgenic plants different cultivars using somatic embryos, seeds, cotyledons, polinic tube, leaf buds or cotyledonary leaves early stages development particle bombardment direct inoculation, goal postharvest quality, develop abiotic like salinity dehydration, resistance viruses phytopathogens. As result, several created showing desirable phenotypic characteristics. In paper available information about improvement reviewed analyzed, focusing on manipulation had utilized aim introduce agronomic traits. portuguesO melao pertence das possui uma ampla diversidade mais no Alem fonte tais carboidratos, orgânicos, minerais possivel cultiva-lo grande do outro cresce em regioes tropicais subtropicais; margem aos produtores manter abastecimento produto No entanto, os enfrentam com insetos, fungos. transformacao podem melhorar tolerância estresses afetam producao, da insercao ajudam combater estes Tem-se esforcos criar muitas embrioes sementes, folhas gemas ou nos cotiledonares inoculacao direta, qualidade pos-colheita fatores salinidade estresse assim tem criado expressando desejaveis.
