Liangyou 003 is Hefei Sancai Organic Agricultural Development Co., Ltd. and Jiangsu Hongqi Seed Co., Ltd. The two-line crosses with male parent Bensandong Sensitive Gene Two-line CMS and LR03 Indica new combination, which can be through the seed bentazone coating or sprayed at the lethal concentration of bentazon seed removal due to temperature self-selfing during the birth of the mother, avoid the purity of the two lines of production affected by temperature changes risks of. The combination of moderate growth period, better leaf morphology, resistance to lodging, high and stable yield, strong resistance, medium quality, high yield seed production. In November 2011, it passed the examination of varieties in Anhui Province and was approved as Wandao 2011013.
