早熟九叶青花椒的选育与分子鉴定

Breeding and Molecular Identification of Zanthoxylum armatum ‘Zaoshu jiuyeqinghuajiao’

摘要: 为选育岀矮化、早熟、早果、丰产、质优的青花椒良种，于2005年开始从九青叶花椒实生繁育群体中选出的优良单株，通过变异单株初选、复选、决选，选育出早熟九叶青花椒良种。该优良品种果实颗粒大，果型指数1.06~1.08，平均千粒重90 g~96 g；种皮麻味素含量16.4 mg·g^-1~16.6 mg·g^-1，醇溶性提取物含量18.6%~19.2%，乙醚提取物含量12.5%~12.9%，蛋白质含量14.8%~15.2%；含挥发性香味物质组分97个，其中特异香气成分物质39个。品质达到或超过国家林业行业标准规定的特级花椒。

Abstract: The excellent individual plants were selected from the seedling variant plants of Z.armatum var.novemfolius in 2005,and then the primary selection of mutant individual plants,second selection and final selection were done.The fruits of Z.armatum ‘Zaoshu jiuyeqinghuajiao’ were large in grain size and its shape index was 1.06 to 1.08.The thousand-grain weight of fresh pepper was 90~96 g.The content of fagaramide was 16.4 mg·g^-1~16.6 mg·g^-1.The extract concentration by alcohol and diethyl ether was from 18.6%~19.2% and 12.5%~12.9%,respectively.The protein content was 14.8%~15.2%.There were 97 components of essential oil,including 39 peculiar components.Its quality had been up or over the national forestry industry standards.
