七个主要子莲品种比较试验研究

A COMPERATIVE RESEARCH ON SEVEN MAIN SEED LOTUS VARIETIES

1987～1990年对7个主要子莲品种采取重点区组对比法进行品比试验,研究结果证明,寸三莲是一个较好的早熟地方品种,湘84-1(湘莲1号)是一个莲蓬大、莲子大而多、品质风味优良的中熟偏早的丰产型品种.大蓬莲、湘白莲、广昌莲、红建莲都是各具特色的地方品种,可供育种上利用.冬瓜莲产量性状和风味品质均较差子.莲单位面积产量构成因素主要有单位面积内有效蓬数、单蓬心皮数、结实率和莲子平均单粒重.提出了莲子产量计算公式,并对子莲生产和科学研究进行了讨论.

We have researched seven main seed lotus varieties for 3 years. The research results indicate that Ceng San Lian is a good early variety but Xiang Lian 1 is better that it. Xiang Lian 1 is a medium variety with high yield, big lotus receptacle and seed. As to Da Peng Lian, Xiang Bai Lian, Guang Chang Lian,Hong Jian Lian, all of them have their own characteristics and can be used in breeding. Dong Gua Lian is a poor variety in both the output and quality. Xiang Lian 1 is the best one among them. The yield components (w) are:number of effective lotus receptacle per unit area(N), carpel number of a lotus receptacle (E) and weight of lotas seed (H).
