Abstract:
Genotype is one of the important factors influencing soybean somatic embryo induction and plant regeneration.Forty one spring soybean cultivars were researched to screen the ideal genotype for somatic embryo induction.The frequencies of soybean somatic embryo was different among tested materials,Kenfeng 23(99.7%) was the highest;nine genotypes,including Hefeng 55,ranged from seventy to ninety percent;five genotypes,including Dengke 4,had no somatic embryos.The somatic embryos of Kenfeng 23 were grape-like and in bright green color.Kenfeng 23,with great number of somatic embryo on each immature cotyledon,did not produce deformity embryos,furthermore,each somatic embryo existed independently.For the other high inductivity cultivars,the somatic embryos number of each immature cotyledon was less than Kenfeng 23,and some cultivars had deformity embryos.
