淮安市淮阴区12个优质籼稻品种(系)农艺性状及品质比较试验

Comparative Trial on Agronomic and Quality Traits of 12 High-quality Indica Rice Varieties(Lines)in Huaiyin District,Huai'an City

为筛选出适宜在淮安市淮阴区种植的高产、优质、抗病、综合性状好的优质杂交籼稻品种,为水稻主推品种提供依据,2021年淮阴区对12个优质杂交籼稻参试品种(系)的生育期、抗逆性、丰产性进行比较试验。结果表明:从综合产量及生育期、抗逆性及田间长势长相看,表现较好的品种有Q两优1606、Q两优532,产量分别为680.0、675.0 kg/667 m^(2),生育期均为149 d,抗逆性较强,田间长势长相较好,可扩大示范种植或推广种植。

The purpose of the present study was to select excellent hybrid indica rice varieties that have a high-yielding capacity,high quality,disease resistance,fine comprehensive traits,and suitability for planting in Huaiyin District of Huai'an City.This will lay a foundation for determining the main cultivation varieties of rice in this area.In 2021,a comparative trial was conducted in Huaiyin District to evaluate 12 high-quality hybrid indica rice varieties(lines)with respect to growth period,stress resistance,and yielding capacity.In terms of comprehensive yield traits,growth period,stress resistance,and field performance,the hybrid indica rice varieties Q-liangyou 1606 and Q-liangyou 532 both exceeded the other tested varieties,attaining the yields of 680.0 and 675.0 kg/667 m^(2),respectively,and having the same growth period of 149 days,strong stress resistance,and good field performance.Thus,Q-liangyou 1606 and Q-liangyou 532 are suitable for a large-scale demonstration planting or promotion.
