协优华联2号是协青早A和华联2号配置的早稻中迟熟杂交组合。经我市1990年在金星村杂交早稻新组合品种对比试验中,平均亩产556.3公斤。比对照组合协优49平均亩产高58.6公斤,增产11.7%;比威优华联2号平均亩产高29.0公斤,增产5.5％。居第一位。在大田生产中,该组合最高亩产达679.1公斤。全生育期间119～120天,叶龄14.3,株高90.5cm,穗长19.5cm,每穗点粒数107.3粒,结实率85.6％,千粒重26.5克。且分蘖力强、耐肥、抗倒伏、抗稻瘟、中抗纹枯病、产量高等恃点。是当今双季杂交吨粮田可供选择的优良组合之一。
Xieyou Hualian No.2 is a hybrid combination of late early maturing hybrid rice arranged by Xieqingzao A and Hualian No.2. In 1990, the city of Jinxing hybrid early hybrid rice varieties tested, the average yield of 556.3 kilograms. Compared with the control group, the average yield per acreage of Xieyou 49 was 58.6 kg, an increase of 11.7%. The average yield per mu of Weiwei Union W 2 was 29.0 kg, an increase of 5.5%. In the first place. In the Daejeon production, the highest yield of the combination reached 679.1 kg. The whole growth period of 119 to 120 days, leaf age 14.3, plant height 90.5cm, spike length 19.5cm, grain per panicle 107.3, seed setting rate 85.6%, 1000 grain weight 26.5 grams. And strong tillering, resistance to fertilizer, lodging, resistance to rice blast, resistance in sheath blight, high yield and other advantages. It is one of the finest combinations to choose from today’s two-season hybrid grain crop.
