Increased grain protein and gluten contents of bread wheat caused by introgression of a T. timopheevii segment into chromosome 2A
The end use and value of bread wheat grain is determined by its protein and gluten content. Therefore, stable manifestation of this trait in a...
-
Anchoring alien chromosome segment substitutions bearing gene(s) for resistance to mustard aphid in Brassica juncea-B. fruticulosa introgression lines and their possible disruption through gamma irradiation
Key messageHeavy doses of gamma irradiation can reduce linkage drag by disrupting large sized alien translocations and promoting exchanges between...
-
Identification and substitution mapping of QTLs for anaerobic germination in rice
Hypoxia is a key limiting factor for seedling emergence and establishment of direct-seeded rice (DSR) under submergence. The anaerobic germination...
-
Alteration of root and shoot morphologies by interspecific replacement of individual Upland cotton chromosome or chromosome segment pairs
Genetic approaches often lead to the most cost-effective and efficient means to improve crops, especially those grown widely. But for most crops,...
