List two problems associated with breeding for drought tolerant sorghum

List two problems associated with breeding for drought tolerant sorghum

Answers

Faith
1. Many xerophytic features tend to be irreconcilable with high productivity. For instance reduced or highly specialized leaves or very low transpiration rate means low yields and may be inconceivable for a commercial farmer interested in maximizing his yields.
2. Breading for drought resistance as such is a long term, is complex and governed by large number of genes which is difficult to combine in a desirable way. Furthermore in sorghum, genotypic traits that govern drought resistance are not all as heritable as stomatal frequency and size and therefore are not subject to genetic manipulation.
