The Rht13 dwarfing gene reduces peduncle length and plant height to increase grain number and yield of wheat
The green-revolution Rht-B1b and Rht-D1b dwarfing alleles are usually associated with increased wheat yields but are linked to reduced early growth and poor emergence if sowing conditions are unfavourable. Other dwarfing ...
Characterization of Chinese wheat germplasm for resistance to Fusarium head blight at CIMMYT, Mexico
Fusarium head blight (FHB) poses a challenge for wheat breeders worldwide; there are limited sources of resistance and the genetic basis for resistance is not well understood. In the mid-1980s, a shuttle breeding and ...
Assessing morphological and genetic variation in annatto (Bixa orellana L.) by sequence-related amplified polymorphism and cluster analysis
Annatto (Bixa orellana L.) is the sole source of bixin, a seed-specific red apocarotenoid pigment used worldwide. Genetic improvement of annatto has focused on increasing bixin content as well as fostering traits that favor ...
Height reduction and agronomic performance for selected gibberellin-responsive dwarfing genes in bread wheat (Triticum aestivum L.)
Improved ability to establish well when sowing at depth, into crop residues or hard soils should lead to increased yields in these situations. The semi-dwarfingRht-B1b and Rht-D1bgenes reduce plant height and increase grain ...
