Heterosis for grain yield and its parameters in Kharif sorghum [Sorghum bicolor (L.) Moench ] hybrids

Heterosis and Combining Ability Studies in Sorghum (Sorghum bicolor (L.) Moench) Over the Environments

In the field of plant breeding, the most important breakthrough has been considered as ‘heterosis’. Exploitation of heterosis on commercial scale and the systematic varietal improvement through hybridization are the main tools to increase the sorghum production. The success in the development of superior hybrids and/or varieties depends on the choice of parents for hybridization and amount and ...

Analysis of grain yield stability and assessment of genotype × environment interaction for grain sorghum (Sorghum bicolor L. Moench) genotypes

The interaction of genotype × environment creates complications in yield prediction and is a challenge for agronomy and plant breeding programs. To evaluate grain yield stability and genotype × environment interaction for 18 local and exotic grain sorghum cultivars, lines, and hybrids, a field experiment was conducted using randomized complete block design with three replications in four region...

Molecular mapping of QTLs conferring stay-green in grain sorghum (Sorghum bicolor L. Moench).

Drought resistance is of enormous importance in crop production. The identification of genetic factors involved in plant response to drought stress provides a strong foundation for improving drought tolerance. Stay-green is a drought resistance trait in sorghum (Sorghum bicolor L. Moench) that gives plants resistance to premature senescence under severe soil moisture stress during the post-flow...

Modulation of kernel storage proteins in grain sorghum (<i>Sorghum bicolor</i> (L.) Moench)

Modulation of kernel storage proteins in grain sorghum (Sorghum bicolor (L.) Moench).

Sorghum prolamins, termed kafirins, are categorized into subgroups α, β, and γ. The kafirins are co-translationally translocated to the endoplasmic reticulum (ER) where they are assembled into discrete protein bodies that tend to be poorly digestible with low functionality in food and feed applications. As a means to address the issues surrounding functionality and digestibility in sorghum, we ...
