By means of intervarietal crossing and linear selection, the new rape variety "Youyan No. 1" of low erucic acid and "Youyan No. 2" of "Double Low"(low erucic acid and low glusosiolate) have been bred.
The very strong " value added " of our proposal live in the character not only crossing housing, but in the potential of use which offers the device of " double loggia " on rooms to be lived.
On the first floor, four bedrooms with double brick wall insulated and timber sliding louvers to prevent from direct sun light and allow crossing ventilation.
