Summary: By studying the progeny of a cross between two bean cultivars, four genetic loci that affect epicotyl length were found, and the chromosomal location of one of these loci was narrowed down using molecular markers, which can be used for selecting bean cultivars with longer epicotyls that are suitable for mechanical weeding and harvesting.

Summary: This study identified broad resistance to Zymoseptoria tritici in the Tunisian durum wheat landrace accession 'Agili39' and mapped two major and two minor QTL associated with the resistance. The findings suggest that the natural pyramiding of these QTL in 'Agili 39' contributes to its broad efficacy against STB and can be utilized for effective breeding of Z. tritici resistance in durum wheat.

Summary: This study aimed to map quantitative trait loci (QTL) responsible for the expression of FHB resistance in two adapted cultivars and evaluate their co-localization with agronomic traits. It was found that FHB resistance QTL co-localized with QTL for plant height, days to heading, and days to maturity. Selecting for improved FHB resistance within adapted cultivars can be done by using markers associated with complementary QTL.

Summary: The study combined a fast breeding approach with intensive phenotypic selection to detect QTLs controlling Fusarium crown rot resistance in wheat. They identified 17 genomic regions associated with the response to selection, including both known QTLs and potentially novel regions contributing to resistance. The study demonstrated that QTL detection in breeding populations under selection can identify and increase the frequency of favorable alleles, providing valuable information for breeding applications.

Summary: This study identified genetic loci, SNP markers, and candidate genes associated with the hull-less trait in pumpkin using the QTL-seq approach. A single QTL on chromosome 12 was significantly associated with the trait, and two SNP markers were identified as significantly correlated with the hull-less trait in different genetic backgrounds of pumpkin. Candidate genes included those involved in cell wall deposition and lignin accumulation. These findings will facilitate marker-assisted selection for the hull-less seed trait in pumpkin.

Summary: The study identified QTL for spike density in wheat, providing a genetic basis for optimizing spike structure. Major and stable QTL were discovered, along with analyses of QTL x environment effects and epistatic interactions for spike density. Pyramiding analysis revealed additive effects between specific QTL, and correlations with agronomic traits such as spike length and kernel length were observed. Several genes related to spike development within major or stable QTL intervals were predicted. Overall, the research broadened the genetic basis of spike density and identified QTL with potential applications in modern wheat breeding.

Summary: The study assessed 2,403 Iranian wheat landrace accessions (IWAs) from CIMMYT's genebank using DArT-seq technology to evaluate genetic diversity. A core-set representing 15% of the hexaploid wheat accessions was selected, capturing 93% of rare alleles. The core-set was validated across multiple locations and identified potential donor accessions for disease resistance and zinc concentration traits in wheat breeding. The study demonstrates a breeder-friendly strategy for utilizing genetic variation stored in genebanks.
