| Abstract:
The Maryland/Virginia/New Jersey/Wisconsin Rubus breeding program is attempting to provide cultivars capable of withstanding the temperature extremes (-30°C to +40°C) of a humid continental climate. The use of various species and a wide range of cultivars is providing adapted selections. Further progress is being made through the use of tissue culture-assisted ploidy manipulation and genetic engineering. Critical to these protocols have been techniques to regenerate shoots from leaves. Recent advances have consistently resulted in over 90% successful regeneration from the apical-most leaflets. | |
