alleles; blight; breeding lines; chickpeas; ethylene; genetic markers; heterozygosity; phenotype; quantitative trait loci
Abstract:
... A new co-dominant molecular marker, CaETR, was developed based on allelic sequence length polymorphism in an ethylene receptor-like gene located in the genomic region of a QTL (QTLAR₁) conferring ascochyta blight resistance in chickpea. This marker not only discriminated resistance and susceptible phenotypes of chickpea to ascochyta blight, but also easily detected heterozygous genotypes. Using th ...

Abstract:
... Seed coat wrinkling is a major factor affecting the germinability of soybean [Glycine max (L.) Merr.] seed produced in high-temperature environments, such as in the Early Soybean Production System of the midsouthern United States. Exposure of seed to high temperatures, coupled with alternating periods of wet and dry conditions, promotes seed coat wrinkling. This can predispose the seed to mechanic ...

Abstract:
... The analysis of multiples traits has been largely employed in animal and forestry crop breeding; however, in annual crops such as common bean this approach is practically lacking. This study examined the selective accuracy and estimates of genetic parameters in common bean using single- and multi-trait analyses in several designs of genetic correlations and heritabilities by means of simulated- an ...

Abstract:
... Phosphorus (P) is an essential macronutrient required for many biological and metabolic plant functions. Phosphate is the form of P used by plants. Reducing the amount of P in the seed can further aide breeding efforts to reduce the amount of P released into the environment due to the indigestibility of the complexes formed with metal ions. Analysis of the variation of phosphorus concentration in ...

A homozygous resistant genotype WR315 (h₁h₁ h₂h₂) was crossed to two susceptible lines, Karikadle (H₁H₁ H₂H₂) and BG256 (h₁h₁ H₂H₂), to generate two different F₁ populations. Three F₁ plants from each cross were subjected to gametophytic s ...

The mode of gene action conferring resistance to the virus is not well understood. The objective of the study was to determine the genetic inheritance of resistance in cowpea crosses. Three susceptible (S) cowpea landraces that are commonly grow ...
