Analysis of homeolog specific transcription in hexaploid wheat
(Master thesis, 2013-09-23)Bread wheat (Triticum aestivum, BBAADD) is one of the most important food-crops world-wide. The genome of bread wheat is allohexaploid, meaning that it contains three related diploid genomes (termed A, B and D). This implies ... -
Assessment of pre-harvest sprouting resistance in spring wheat in Norway
(Master thesis, 2012-09-17)Pre-harvest sprouting is the precocious germination of kernels while still in the mother plant due to early breakage of seed dormancy, which usually occurs when humid weather conditions persist before harvest. It causes a ... -
