A study on genetic aspects of seed dormancy
Journal Title: International journal of Advanced Biological and Biomedical Research - Year 2014, Vol 2, Issue 1
Abstract
Changes in seed dormancy were selected during the domestication of crop plants from wild-plant species, because some features of dormancy that provide ecological advantages presented agronomic disadvantages within a farmed system. Seed dormancy varies widely among seed batches, even for seeds of the same genotype, indicating large environmental influences. For genetic studies, it is essential to obtain such quantitative data on seed material without the effects of variation in environmental conditions, including the maternal growing and seed storage conditions. The genetics of seed dormancy is as predicted on Mather's theory of genetical architecture for a character that has been subject to strong directional selection. Many studies on the genetics of seed dormancy regulation have concluded that dormancy is a quantitative trait controlled by multiple loci that affect different seed tissues, and often different aspects of seed physiology. Therefore, in this study discos on some research on seed dormancy control by genetic.
