A method for breeding Stevia rebaudiana with a high content of RA comprises selecting the plants in the perfect stage with a high RA content as parents and hybridizing them to produce F1 generation seeds; stabilizing the traits of the F1 generation in the imperfect stage; producing F2 generation seeds by a backcross method and optionally producing F3 generation seeds by a further backcross method.

A storage box for storing power tool bits comprises a container, a bit holder and a control device. The container defines a compartment in which is received the bit holder along a common rotary axis. The bit holder comprises a plurality of outwardly radial pockets for receiving bits. The control device selectively disengages from the bit holder so that the bit holder is rotational about the common axis to move the bits rotationally in and out of the compartment.

The present invention relates to a portable blower-vacuum device which comprises a motor (3) operated by a switch (7) and located in a main body (2) and a fan (4) drivable by the motor. A vacuum nozzle (11) and a blower nozzle (12) are associated with the main body and the vacuum nozzle comprises a main portion (14a) extending in a direction of an axis (Z1) of the main portion and a terminal portion (14b) with an axis (Z2) angularly disposed with respect to the axis (Z1) of the main portion.
