摘　　要：2008年在通榆县兴隆山镇林场甜仁用杏‘龙王帽’生产园采种,2009年春季播种,2013年全部结果,从种子苗中筛选出2个甜仁优良无性系,优系‘23号’和优系‘24号’。结果表明:2个优系均具有早期丰产性好、抗寒性强。优系‘23号’单仁质量0.802g,出仁率38.74%;优系‘24号’单仁质量0.764g,出仁率42.44%,2个优系出仁率均高于‘龙王帽’(31.85%);以山杏幼树为砧木进行嫁接,第2年结果产量均超过‘龙王帽’,通过调查嫁接后生长量和长枝数量,发现2个优系新梢生长量比‘龙王帽’低,但长枝数量比‘龙王帽’多,并总结了2个优系的栽培技术要点。In 2008,seeds of sweet almond apricot ＇Longwangmao＇ were collected in orchard of Tongyu county Xinglongshan town forest farm,then the seeds were planted in the spring of 2009 and beat fruit in 2013.The results showed that two clones of sweet almond apricot were selected from seed seedlings,which had the characteristics of early high yield and strong cold resistance.Among them,the single nut weight of ＇No.23＇ was 0.802 g and the shelling percentage was 38.74%,the single nut weight of ＇No.24＇ was 0.764 g and the shelling percentage was 42.44%,the shelling percentage of the two clones was higher than those of apricot-＇Longwangmao＇（31.85%）;the two clones were grafted on the saplings of Prunus sibirica,fruit yield were more than ＇Longwangmao＇ in the second year,and growth and branches number of grafted seedlings were also investigated,the results showed that shoot growth was lower than ＇Longwangmao＇,but the number of long branches was more than ＇Longwangmao＇.Finally,the main cultivation techniques of the two clones ＇Longwangmao＇ was summarized.
