“田两优 40 2” ,原名F1 31S/R40 2 ,是赣州市农科所育成的一个两系法籼型杂交早稻组合。母本“田丰S”是该所育成的籼型两用核不育系 ;父本R40 2是湖南安江农校选育成的三系法早杂恢复系。该组合全生育期 1 1 5d左右 ,分蘖力较强 ,穗粒结构、丰产性、抗性、熟期都较好。从 1 996年起在省内外试验、试种和示范均表现出明显的增产优势。是一个高产稳产、抗性较强、米质较优的两系籼型杂交早稻新组合。 1 998年通过江西省农作物品种审定委员会审定 ,命名为“田两优 40 2” ,母本F1 31S命名为“田丰S”。
“Tian Liang You 40 2”, formerly known as F1 31S / R40 2, is a two-line indica hybrid early rice combination bred by Ganzhou Agricultural College. The female parent “Tian Feng S” is the bred dual-purpose nuclear male sterile line. The male parent R40 2 is a three-line early-restoring restorer line selected by Hunan Anjiang Agricultural School. The combination of the whole growth period of about 115d, strong tillering ability, grain structure, high yield, resistance, maturity are better. From 1996 onwards, both inside and outside the province have demonstrated significant stimulation advantages in trial planting and demonstration. It is a new combination of two-line indica hybrid rice with high yield, stable yield, strong resistance and better grain quality. In 1998, it was approved by Jiangxi Provincial Crop Variety Approval Committee and named as “Tian Liang You 40 2”. The female F1 31S was named “Tian Feng S”.
