Studies on the breeding of deep yellow flowered cyclamen cultivars

为了选育深黄花仙客来品种，本研究以黄花仙客来与色素积累型仙客来（黑篝火）杂交，对黑篝火及其F_1代的花色和色素组成进行了研究.‘黑篝火’：该品种的花呈黑红色，花瓣中含有大量的花青素。从其花瓣中检测到飞燕草素、矮牵牛素、锦葵素、矢车菊素和芍药素，而正常的“篝火”花为红色，花瓣中含有矢车菊素和芍药素。用黄花仙客来与黑篝火杂交，获得40个F_1代，未能获得黄花，但获得了粉红色或紫色花的F_1代。1.3.F_1的色素组成：在粉红色花的F_1中检测到飞燕草色素、锦葵色素和矢车菊色素，在紫色花的F_1中检测到飞燕草色素和锦葵色素。虽然黄花仙客来的主要药剂是查耳酮，但F_1代中均不含这种色素。

Crossing between yellow flowered cyclamen and pigment accumulation type cyclamen('Black Bonfire')were done for the breeding of deep yellow flowered cyclamen cultivars.The flower color and the pigment constitutions of 'Black Bonfire'and F_1 offsprings were investigated.1.'Black Bonfire' : The flower of this cultivar showed black red and contained high amount of anthocyanin in its petals. And delphinindin,petunindin,malvidin,cyanindin and peonidin were detected from its petals,whearas normal 'Bonfire'showed red flower and contained cyanidin and peonidin in its petals.2.Flower color of F_1 : Fouty F_1 offsprings were obtained from the crossing between yellow flowered cyclamen and 'Black Bonfire'.We could not obtain yellow flowered F_1 offsprings but obtained pink or purple flowered F_1.3.Pigment constitutions of F_1 : Delphinidin malvidin and cyanidin were detected from the pink flowered F_1 and delphinidin and malvidin were detected from the purple flowered F_1. Although the main agent of yellow flowered cyclamen was chalcone,this pigment was not contained in any F_1 offsprings.
