中文摘要

The papaya (Carica papaya L.) is one of the most important economic tropical fruits in the world, and the hermaphrodite is the preferred type in field cultures. We analyzed the sexual ratio of offspring from the cultivar ‘Taiwan Seed Station No. 7’ (T7) by a self-cross and its cross with Taichung Sunrise (TS). Female progeny from the T7 self-crossing were not observed. This finding may be caused by a lethal gene that is linked to females. In this study, we selected 192 simple sequence repeats (SSRs) to analyze the polymorphism between T7 and TS. A total of 37 SSRs were identified for T7 and TS. In addition, 14 SSRs served as the molecular makers for identification of T7, TS and their hybrid offsprings. Thus, the results show that the
genetic similarity between T7 and TS is rather high. This suggests
that T7 may be a mutant of TS. Phylogenetic analysis from the SSR
polymorphisms of the above parent strains and 15 F1 offspring revealed
the genetic distance of the F1 offspring located between T7 and TS.
The results of this study may provide an opportunity for elucidating
the genetic characteristics of all hermaphrodites via identification of
molecular makers.
