A cytoplasmic male sterileplant is provided having a growth ability equivalent to that of aplant having a normal cytoplasm or a progeny of the cytoplasmic male sterileplant. For example, it is possible to improve the deterioration of growth ability which has been observed in the conventional cytoplasmic male sterileplants and provide a cytoplasmic male sterileplant having an improved growth ability.

Cytoplasmic male sterileplant having improved growth ability

A method is provided of producing aplant seed including using abee as pollination means, and providing the abee a minor nectar plant to have preference in flower visiting, in addition to a pollen parentplant and a seed parentplant and to perform a crossing of aplant using a plant species having the preference in flower visiting equivalent to or lower than that of theplant. According to one embodiment, it is possible to produce ahybrid plant seed more efficiently and economically than before while using abee as pollination means.

Method of producingplant seed using a Megachile bee

The present invention relates to a novelhaving cytoplasmic male sterility and a method for breeding the same. More specifically, the present invention relates to a novelhaving cytoplasmic male sterility, wherein thesubstantially lacks pollen production functions due to insufficient stamen or pollen formation, and a method for breeding the same.
