    Notes: Summary Interspecific hybrid clover plants from the cross Trifolium sarosiense Hazsl. X T. pratense L. were obtained in the present investigation. Immature hybrid embryos were excised aseptically from the pistillate parent, T. sarosiense (2 n = 48), and cultured in vitro prior to in situ abortion. Agar-solidified nutrient media modified from that developed previously for tissue and cell cultures of red clover (2 n = 14) were used for embryo rescue. The heart shaped embryos obtained were cultured for 8 to 14 days on a medium containing a high level of sucrose, a moderate level of auxin, and low cytokinin activity. Viable embryos were then transferred to a standard medium with low auxin and moderate cytokinin levels for the direct germination of shoots. Some embryos produced only callus. Plants were regenerated from callus using an alternate culture scheme. Hybrid shoot numbers were increased on a low auxin, high cytokinin medium and subsequently rooted before transfer to soil in the greenhouse. About 10% of the hybrid embryos were rescued using the optimal culture sequence. Five full-sib families of the F1 hybrid were successfully grown to maturity. Root-tip cells of hybrid plants possessed the expected somatic chromosome number of 31. The genetically determined leaf-mark trait carried by the staminate parent and the rhizomatous root habit of the pistillate parent were expressed in hybrid plants.

    Notes: Abstract Glycine max (L.) Merr. (soybean) andGlycine soja Sieb. and Zucc. cell suspension cultures were grown and used as inoculum sources for growing callus on agar-solidified nutrient media. Concentrations and chemical forms of the growth regulators in liquid and solidified media were altered in an attempt to achieve in vitro plant regeneration. Numerous embryoids, particularly ofG. soja, were produced on basal nutrient media supplemented with 100 ppm casein hydrolysate, 0.1 μM abscisic acid, 2.25 μM 2,4-dichlorophenoxyacetic acid, and 15 μM adenine or 0.46 μM kinetin. Often the roots of the embryoids elongated. This was enhanced in the presence of an inhibitor of gibberellin synthesis (1 to 20 μM Amo 1618). Callus recovered from aG. soja suspension culture produced one shoot structure when grown on a solid medium containing 0.2 μM Amo 1618 and 80 μM glutathione. The shoot structure consisted of two distinct buds, one producing two leaves. The shoot did not develop into a plant. Although regeneration of soybean plants was not achieved, these observations suggest that it may be achievable.
