摘要
以非洲菊品种及其胚珠诱导培育的双单倍体为试验材料,采用田间完全随机排列方法,对开花植株的花色、花序类型和花心颜色进行观测,解析非洲菊的花序遗传表现,以期为非洲菊定向育种的亲本选择提供参考依据。结果表明:非洲菊的花色和花心表现为偏母性遗传趋势,其中红色品种的后代双单倍体植株花色和母本植株一致的概率达95%以上,花心颜色与母本植株一致的概率达55%以上;单瓣品种后代双单倍体植株的花序类型偏母性遗传倾向明显,和母本植株一致的概率达90%以上;重瓣和半重瓣品种后代双单倍体植株的花序类型未表现出明显的偏母性遗传倾向,和母本植株一致的概率不到35%。
Taking Gerbera hybrida varieties and their double haploids induced from ovules as the test materials,the field completely random arrangement method was used to observe the flower color,inflorescence type,and flower center color of flowering plants,and analyzed the genetic performance of Gerbera hybrida inflorescence,in order to provide reference for parental selection in directional breeding of Gerbera hybrida.The results showed that the color of the flower petal and flower center of Gerbera hybrida showed a tendency towards maternal inheritance,and the probability of over 95%for the offspring of red varieties with double haploid plants to have the same flower color as the maternal plant,and the probability of flower center color being consistent with the maternal plant was over 55%.The inflorescence types of double haploid plants in the offspring of single petal varieties had a significant tendency towards maternal inheritance,and the probability of being consistent with the maternal plants was more than 90%.The inflorescence types of double haploid plants derived from double petal varieties and semidouble petal varieties did not show a significant maternal tendency,and the probability of being consistent with the maternal plants was less than 35%.
