Clonally Propagated and Seed-derived Papaya Orchards: II. Yield Comparison

Abstract: Gynodioecious papaya (Carica papaya L.) seedlings in commercial cropping systems in Hawaii are typically multiple-planted and thinned upon fl owering to a single hermaphrodite because seedlings segregate for sex expression. Use of clonally propagated hermaphrodites would eliminate the over-planting practice and may provide other advantages. Yields of clonally propagated hermaphrodites were compared with single-and multiple-planted seedlings in three fi elds on two islands in Hawaii. Cloned hermaphrodites were … Show more

“…Generally, female papayas had a smaller shape index and greater mass than the hermaphrodite fruits ( P < 0.05; Table ); this is not unexpected since in comparison to hermaphrodite fruits female papayas are typically more compact . There were no significant differences in the shape index (Table ) of the female non‐transgenic and transgenic papayas; however, for the hermaphrodite fruits only transgenic line 52.22 was similar to the non‐transgenic papaya in shape.…”

“…No hubo variación entre plantas de ambos métodos de sexado para estas variables. Los resultados obtenidos en el presente estudio coincidieron con lo determinado por Fitch et al (2005b) para el híbrido Rainbow; pero difirieron de los resultados de Salinas et al (2018) para el cultivar BH-65, quienes observaron que los frutos de plantas SM presentaron una mayor longitud y diámetro en comparación con frutos de plantas SC.…”

“…El efecto del sistema de sexado sobre el rendimiento de plantas de papaya parece depender del genotipo. Para el híbrido Rainbow no se encontraron diferencias significativas para el rendimiento entre plantas SC y SM, en dos localidades en Hawaii (Fitch et al, 2005b), lo que coincide con lo observado en el presente estudio; mientras que, para el cultivar BH-65 el rendimiento comercial de plantas SM fue aproximadamente 49 % mayor que el de plantas SC (Salinas et al, 2018).…”
