Influence of heat stress on grain yield, grain quality, and protein composition of spring wheat

Creator:

Castro Derényi, Marina

Abstract:

Wheat (Triticum aestivum L.) plants exposed to higher than usual temperatures during ripening show altered agronomic and grain quality characteristics. Given that seasonal variation in quality creates difficulties in the marketing and processing of grain, improving the genetic adaptation of wheat cultivars to heat stress is an important objective in...

Jointed goatgrass (Aegilops cylindrica Host) genetic diversity and hybridization with wheat (Triticum aestivum L.)

Creator:

Gandhi, Harish Tulshiramji

Abstract:

Jointed goatgrass (Aegilops cylindrica Host; 2n=4x=28; CCDD) is an agriculturally important species both as a weed and as a genetic resource for wheat (Triticum aestivum L.; 2n=6x=42; AABBDD) improvement. In order to better understand the evolution of this species, the diversity of Ae. cylindrica was evaluated along with its progenitors,...

Small broomrape (Orobanche minor) biology and management in red clover (Trifolium pratense) seed production

Creator:

Lins, Ryan D.

Abstract:

Small broomrape (Orobanche minor) is a parasitic weed that attaches to the roots of red clover (Trifolium pratense). Small broomrape invasion presents a significant threat to the future of red clover seed production in Oregon. This study was conducted to investigate and develop small broomrape management options for red clover...
