A NEW TYPE OF FUNCTIONAL MALE STERILITY DERIVED FROM INTERSPECIFIC HYBRID

A simple plant showing a new type of functional male sterility was found in backcross derivatives of the hybrids L. esculentum Mill. and L. parviflorum Rick et al.. This plant also had a characteristic shape of cotyledones and leaves.
All these characters – the male sterility and characteristic shape of cotyledones and leaves – are inherited jointly and depend on the interaction of three recessive genes.

Plants with this new type of functional male sterility ensured a sufficient level of cross polination.
The characteristic cotyledon shape of this stock is of special benefit.
Owing to this, seedlings from accidental self-pollination and F₁ hybrids can be easily distinguished.

This new type of functional male sterility permits to reduce costs of the production of F₁ hybrids seeds.
