genotypic variation for traits associated with dry matter remobilization in grain sorghum (sorghum bicolor l. moench) genotypes under drought stress conditions

Genotypic variation in sorghum [Sorghum bicolor (L.) Moench] exotic germplasm collections for drought and disease tolerance

Sorghum [Sorghum bicolor (L.) Moench] grain yield is severely affected by abiotic and biotic stresses during post-flowering stages, which has been aggravated by climate change. New parental lines having genes for various biotic and abiotic stress tolerances have the potential to mitigate this negative effect. Field studies were conducted under irrigated and dryland conditions with 128 exotic ge...

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...

Correlation studies for shootfly resistance traits in sorghum (Sorghum bicolor (L.) Moench)

A field experiment was conducted to study the relation of different plant characters and shoot fly resistance in sorghum. Leaf glossiness showed high positive correlation with shootfly oviposition and dead hearts. The oviposition percentage on 14 and 21 days after seedling emergence exhibited significant positive correlation with dead hearts. Leaf trichome density on adaxial and abaxial leaf su...

Assessing sorghum [Sorghum bicolor (L) Moench] germplasm for new traits: food, fuels & unique uses

Sorghum [Sorghum bicolor (L) Moench] is the fifth most important cereal crop in the world; however, it has a wide range of other applications that are being explored with worldwide interest in renewable resources. The USA sorghum germplasm collection contains over 41,000 accessions that represent landraces and cultivars from over 115 countries. Traditionally, this collection has been evaluated ...

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...
