Description
Burak Ayık and co-authors assess, in twenty twenty-four, wheat lines bred for resistance to pre-harvest sprouting, using speed breeding. Sprouting in the ear before harvest ruins grain quality. Resistance is tied to seed dormancy genes. The team crossed a resistant variety, Rio Blanco, with three other lines, and carried resistance regions into backcross generations. Plants grew under accelerated conditions in a greenhouse and a growth room. They measured plant height, spike length, grains per spike, grain weight, and maturity. Germination tests then flagged dormant lines.
Greenhouse plants performed better than growth room plants. Eleven, eight, and six lines from the three crosses showed notably low germination, a dormancy sign. The first cross had the lowest germination index. Growing conditions strongly shaped trait expression, they conclude.
