Insect resistance is a trait lacking for most of the economically
important insect pests in pea and other grain legumes . This makes improvement efforts
very difficult through conventional breeding. This limitation can
be overcome by transgenic approaches, i.e., by introducing trans-genes for insect resistance from other sources. Preferably,crygenes
from the soil bacterium, Bacillus thuringiensis,are the most com-monlyusedgenes for thedevelopment of insect resistant transgenic
crops
