“…Among the disadvantages of the cultivar there are susceptibility to the ringspot virus of papaya (PRSV, Papaya Ringspot Virus) and bacteriosis caused by Erwinia sp. (Hernández et al, 2019;Maselli et al, 2010;Rodríguez et al, 2013). The main purpose of plant breeding of papaya throughout the world has been to provide stable production by conferring resistance Rev.…”

“…Esto por efecto de reducción del rendimiento de fruta por hectárea, lo cual reduce el ingreso neto por hectárea hasta 275% (Yorobe, 2009). El mayor impacto en la producción de papaya se debe, principalmente, a que ninguna de las variedades comerciales presenta resistencia genéti-ca al PRSV-P y al PMeV (Abreu et al, 2014;Singh et al, 2005); sin embargo, se ha reportado que algunas variedades no comerciales presentan bajos niveles de susceptibilidad (Rodríguez et al, 2013).…”

“…The highest impact on papaya production is mainly due to the fact that none of the commercial varieties has genetic resistance to PRSV-P or PMeV (Abreu et al, 2014;Singh et al, 2005). However, some non-commercial varieties have been reported to have low levels of susceptibility (Rodríguez et al, 2013).…”
