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...
متن کاملEffect of temperature on seed setting behaviour in rabi sorghum (Sorghum bicolor (L). Moench)
Pollen viability is an important parameter of yield as for as interaction of temperature with seed setting is concerned. Rabi sorghum is one of the major cereal crops after rice, wheat and maize. In sorghum seed setting is affected when the flowering period coincides with minimum temperature. In this context comparison was made with pollen fertility percentage and seed setting percentage vs min...
متن کاملHeterosis 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 ...
متن کاملCorrelation 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...
متن کاملMolecular 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...
