In-Depth Information
The information generated from these experiments can be used in breeding programs to select
drought resistant progeny using marker assisted selection. In addition the use of genetic
engineering of select genes is another potentially successful approach to obtaining new
varieites with improved drought resistance or enhanced WUE. With increasing competition
between agriculture and urban populations for fresh water and with climate change which
predicts increasing episodes of intense drought periods worldwide, there is a critical need for
the development of crop varieties with more efficient use of water and the ability to survive
longer drought periods. Since apples are a good source of nutrition and can be conveniently
stored and shipped, they are a logical target for improvement.
