钟花樱桃遗传变异及优良家系选择

Genetic Variation and Excellent Family Selection of Cerasus campanulata

  • 摘要: 以树高和胸径为选育目标对钟花樱桃Cerasus campanulata 进行优良家系选择,于2013 年4-5 月采集福建省62 个家系种子进行育苗,2014 年1 月在浙江省龙游县林场和开化县林场进行造林,2019 年12 月调查各家系树高、胸径等生长性状。测定结果表明,钟花樱桃在两个试验点均生长良好,6 年生家系间树高和胸径变异系数较大,树高和胸径变异系数在开化县林场分别为8.20% ~ 27.34%和8.90% ~ 36.10%、在龙游县林场分别为6.93% ~25.44%和10.39% ~ 31.77%。参试家系间受遗传因素和环境因素的显著影响,生长性状在家系、地点、家系×地点、家系×重复间均存在极显著差异(P<0.01)。供试材料生长性状在家系水平上受到中等强度的遗传控制,在开化县林场、龙游县林场两个试验点树高的单株狭义遗传力分别为0.333 和0.337,胸径单株狭义遗传力分别为0.466和0.303,早期选择能获得较高的遗传增益。从两个试验点家系的胸径生长育种值预测选出同时入选两地的6 个优良家系分别为SY2,ZP28,SM7,SM6,SH41 和YP14。

     

    Abstract: Field collections of seeds of Cerasus campanulata were implemented during April and May of 2013 in 10 counties of Fujian province.62 families of seeds were sowed in July and August of the current year in Longyou and Kaihua of Zhejiang province, and planted in January of 2014.In December 2019, investigation was made on their height and DBH.The results showed that different families of C.campanulata had good growth, with high coefficient of variation of tree height and DBH.The variation coefficients of tree height and DBH were 8.20%-27.34% and 8.90%-36.10% in Kaihua, 6.93%-25.44% and 10.39%-31.77% in Longyou.There were significant differences in growth traits among families, plantation places, families×plantation places and families×repeats(P< 0.01).The growth traits of the tested families were controlled by medium genetic intensity at the family level.Single tree narrow heritability of height and DBH was 0.333, 0.337 and 0.466, 0.303 respectively at Kaihua and Longyou.Early selection could obtain higher genetic gain.Experiment of the two plantations resulted that 6 families were selected by DBH growth.
