Among 33 genes in this study,25 were selected from a cotton somatic embryogenesis SSH array, considered differential expressed at different development stages such as the formation of embryogenic callus and somatic embryogenesis,the others including 5 SERK genes and 3 CKⅡgenes were acquired from the Genebank.

Maize inbreds belonging to 3 maize heterotic groups including Reid, Tangsipingtou and compound germplasm were studied to determine the influence of genotypes, media and plant regulators on the embryo-derived calius induction and green plant regeneration. Immature embryos (1.0~2.0 mm) from selfed ears were harvested as explants. Callus could be induced from all the tested inbreds. However, plant regeneration was only obtained in 12 genotypes.

以Reid、唐四平头和其它种质等3个杂种优势类群共19份玉米自交系为试验材料，以玉米幼胚作为外植体，研究了基因型、培养基和激素对玉米幼胚愈伤组织的诱导及植株再生的影响，结果表明供试材料均能进行愈伤组织的诱导，但是仅有12个自交系能再生植株。N6和改良N6培养基有助于提高愈伤组织的质量及其生长速度。2，4-D在愈伤组织的诱导中起着关键性作用。
