Morphological characteristics of regenerated papaya plants and fruits fromunpollinated ovules

Morphologies of eight papaya (Carica papaya L) plants regenerated from unpo llinated ovules and their fruits were investigated. After growing 6 months in the field, three plants were short, compared with the parental line. Two of these short plants had small trunks and tiny fruits, whereas the third short trees had a large trunk with the first flowers at the lowest position (48cm from the ground level), which developed into the largest and sweetest fruits. One of the dwarfish trees retained its low flowering habits, but t he characteristics of the large and sweet fruit were the same as those of t he parental line. The morphologies of the five other plants were almost the same as those of the parental line.
