A novel synthetic species of Momordica (M. × suboica Bharathi) with potential as a new vegetable crop

A new synthetic species of Momordica (2n = 56) has been developed by crossing natural tetraploid Momordica subangulata subsp. renigera (2n = 56) with induced tetraploid Momordica dioica (2n = 4x = 56). The hybrid produces adventitious root tubers through which it perpetuates and propagates like its female parent and maintains its morphological characteristics in the progeny. The hybrid is naturally fertile and has the superior agronomic traits of both parents making it a good choice as a new vegetable crop. The new species is named Momordica × suboica Bharathi and described.
