Grain yield and its primary determinants, grain number and weight, are important traits in
cereal crops that have been well studied; however, the genetic basis of and interactions …

Sorghum is an important grain crop grown for human consumption worldwide. The crop is
classified into various races with the wild and cultivated sorghums included. The cultivated …

Developing sorghum genotypes suited to post-rainy conditions requires understanding of
the genetic diversity available for grain yield and its component traits. A multi-location trial …

Yield genetic gains have been significantly higher for maize (Zea mays L.) than for sorghum
(Sorghum bicolor L. Moench). Today there is questioning under which environments …

Abstract Knowledge on the genetic bases of physiological processes determining maize
kernel weight (KW) is relevant for maize yield improvement. However, little is known about …

Grain weight has increased during domestication of cereals. Together with grain number it
determines yield, but the two are often negatively correlated. Understanding the genetic …

Maize kernel weight (KW) is associated with the duration of the grain-filling period (GFD)
and the rate of kernel biomass accumulation (KGR). It is also related to the dynamics of …

Individual kernel weight (KW) is largely genetically determined, and its variability is achieved
through different combinations of rate and duration of kernel growth. Genetic variability for …

Seed development is partitioned into a 'lag'phase, a 'seed filling'phase, and a
'maturation'phase. Transitions between phases correspond to seed water concentration …

Effective plant improvement depends on understanding grain yield genotype by
environment (G× E) interactions. Studies focusing on more heritable (secondary) traits …
