Studies across different crops demonstrated that grain or seed number per unit area (GN m–
2) is the dominant yield component. Although grains or seeds derive from floret or flower …

Identifying traits for improving sink strength is a bottleneck to increasing wheat yield. The
interacting processes determining sink strength and yield potential are reviewed and …

Wheat yield is frequently analysed in terms of yield components (spikes per m 2, grains per
spike, grain size), and correlations between components are commonly reported, but …

Most of the required increases in food production over the next decades are expected to be
achieved through increases in crop yield. As wheat is essential for food security it is worrying …

Further improvements in wheat yields are critical, for which increases in grain number would
be required. In the recent past, higher grain number was achieved through increased growth …

Leaf and floral tissue degeneration is a common feature in plants. In cereal crops such as
barley (Hordeum vulgare L.), pre-anthesis tip degeneration (PTD) starts with growth arrest of …

Grain yields in wheat can be limited by the assimilate supply (source) or by the carbohydrate
demand of the grains (sink). Recently, there have been questions regarding the capability of …

Context Continuing to raise the potential yield of wheat through breeding is essential for
global food security. Past progress has largely been associated with greater grains/m 2 …

Spike fertility traits are critical attributes for grain yield in wheat (Triticum aestivum L.). Here,
we examine the genotypic variation in three important traits: maximum number of floret …

The developmental process of spike is critical for spike fertility through affecting floret
primordia fate in wheat; however, the genetic regulation of this dynamic and complex …
