采用早熟、半矮秆、株型紧凑的波塔姆(Potam S70)与晚中熟、高秆、大穗型的文革一号杂交,选育成早熟、中秆、丰产、抗秆锈病的新品种龙溪35。该品种在漳州全生育期125～130天,株高90厘米左右,每穗结实30～35粒,千粒重45克左右,亩产200～250公斤,高产田400公斤以上。抗杆锈病,轻感叶锈病、白粉病。整齐度好,灌浆性能强,成熟时茎秆落黄好,籽粒饱满,蛋白质含量14.13％,赖氨酸含量为0.35％。龙溪35在1978年至1980年连续三年参加福建省小麦品种联合区域试验,三年34点次累计平均亩产208.8公斤,比对照种晋麦52增产9％,名列第一。1980年冬至1987年春,在闽、粤、陕、蒙等省(区),累计推广面积500多万亩。获得了较大的增产效果与社会经济效益。研究表明,根据漳州的气候条件,小麦育种目标必须突出“早熟”,才能达到丰产。小麦良种龙溪35的育成,说明利用器官发育不平衡的规律,可以通过用不同熟期亲本杂交,并对杂种后代进行培育、选择,把早熟性和丰产性结合在一起,选出既早熟又丰产的新品种。
A hybrid of early maturing, semi-dwarf, compact plant type Potam S70 with the late middle-maturing, tall-stalked and large-spike type Wenchuang No.1 was used to breed new varieties of precocious, middle stem, high yield and stem rust resistance Longxi 35. The varieties in the whole growth period of Zhangzhou 125 to 130 days, about 90 cm tall, 30 to 35 grains per ear, grain weight about 45 grams, 200 to 250 kg per mu, high yield of 400 kg or more. Anti-stem rust, light leaf rust, powdery mildew. Good regularity and strong grouting performance. When ripening, the stalks drop yellow and the grains are full, the protein content is 14.13% and the lysine content is 0.35%. Longxi 35 in Fujian Province from 1978 to 1980 for three consecutive years to participate in joint trials of wheat varieties in Fujian Province, three points 34 points cumulative average 208.8 kilograms per kilogram, compared with the control Jinmai 52 yield 9%, ranking first. The winter of 1980 to the spring of 1987, in Fujian, Guangdong, Shaanxi, Mongolia and other provinces (regions), a total area of more than 5000000 acres of promotion. Obtained a larger stimulation effect and social economic benefits. Research shows that, according to Zhangzhou climatic conditions, wheat breeding objectives must be highlighted “premature” in order to achieve high yield. Wheat elite Longxi 35 bred, indicating the use of organ development imbalance in the law, you can use different maturity of the parental hybrids, hybrids and offspring of breeding, selection, the combination of early maturity and high yield, both elected and precocious High yield of new varieties.
