摘要
1981—1987年的试验证实,利用杂交优势是子莲新品种选育的重要途径。作者通过杂交选育和引种,筛选培育出13号(白花建莲×红千叶)和2号(百叶莲×红花建莲)杂交子莲,杂交优势明显而稳定,其产鼠比对照品种——红花建莲增加20%以上,经济效益十分显著。为了推广这两种杂交子莲,作者还提出了子莲良种繁育时防杂的技术措施。
Experiments were conducted during 1981—1987 on the cross-breeding of seed lotus Ne- lumbo nucifera.The results confirmed the use of heterosis as an important way of selecting new cultivars of seed lotus.Two new cultivars were selected by cross-breeding the introduced cultivars.They are cultivar No.13 (Beihua Jianlian×Hongqianye) and cultivar No.2 (Beiyelian×Honghua Jianlian).The new cultivars show apparant and stable heterosis,with yields 20% higher than that of the control cultivar (Honghua Jianlian).Procedures were proposed for the prevention of undesired hybridization of the new cultivars.
