甜樱桃新品系的选育研究

本试验以5~6 a生的红灯、大紫、抉择等甜樱桃品种的自然授粉的胚培苗为试材,通过对樱桃果实的大小、颜色、可溶性固形物、果肉质地、果汁含量、成熟度等经济性状的观察,明确了优质、自交可孕、不易裂果、耐贮运、适于机械采收、抗病虫、抗寒等现代育种目标,初步选育出几个优株:可溶性固形物高的I-6,平均单果重为2.66 g,最大单果重3.15 g,可溶性固形物为20%;果个较大,丰产性好的I-16,平均单果重为4.57 g,最大单果重6.14 g,可溶性固形物为16%;适于老年人鲜食的,软汁甜樱桃II-15,平均单果重为5.00 g,最大单果重5.71 g,可溶性固形物为17%以及晚熟、色黑果大的III-2,平均单果重为3.48 g、最大单果重3.53 g、可溶性固形物为16%。

Study of Sweat Cherry breeding

Embryo-originated seedings from the 56-year-old Sweat Cherry variaities as Hongdeng,Dazi,Jueze,etc were taken as the materials in this experiment.By observation on the economic traits of fruit size,colour,soluble solid substance,texture,juice content,maturity,the study proved that high quality,self-fertile,cracking-free,easy-to-ship,insect and disease resistant are the main breeding aims.And several elite strains were selected with good traits of the wanted.
