A study on marker-assisted selection (MAS) for the rf1 gene, which controls pollen sterility in the sorghum A1 cytoplasm, was conducted on the offspring population of two crosses between a maintainer line, BTx-622, and two sweet sorghum lines, BJ-299 and Lunen-2, to test the effectiveness of the MAS method and develop maintainer lines with sweet and juicy(More)
Common leaf spot (CLS), which is caused by Pseudopeziza medicaginis (Lib.) Sacc., is one of the most serious fungal diseases occurring in autotetraploid alfalfa (Medicago sativa) worldwide. Polygalacturonase-inhibiting proteins (PGIPs) are important candidate genes for disease resistance studies in plants. The association between an alfalfa PGIP gene,(More)
Polygalacturonase-inhibiting proteins (PGIPs) are leucine-rich repeat proteins involved in plant defence. The aim of the current study was to isolate the genomic fragment of PGIP genes in alfalfa (Medicago sativa) and to analyse their sequence variation. Four PGIP genes, namely MsPGIP1, MsPGIP2, MsPGIP3 and MsPGIP4, were discovered using the homology(More)
A sand culture experiment with Hoagland solution plus NaCl and Na2CO3 was conducted to study the responses of sorghum seedlings to salt-alkaline stress. An assessment method for identifying the salt-alkaline tolerance of sorghum at seedling stage was established, and the salt-alkaline tolerance of 66 sorghum genotypes was evaluated. At the salt(More)
