Summary: This study developed allometric models for estimating enset fiber, kocho, and bula yield, identified yield limiting factors and associated yield gaps. Leaf length, petiole length, and plant height are good indicators for estimating fiber and kocho yields. Soil chemical characteristics differentially impact enset yield attributes, and careful targeting can enhance different yield attributes.

Summary: This study aimed to determine the population structure of a diverse panel of common bean genotypes and deduce associations between bean fly resistance and agronomic traits based on single nucleotide polymorphism (SNP) markers. Through phenotyping and genotyping, significant variations were found in disease severity, mortality rate, pupa count, and other agronomic traits among the genotypes. The genotypes were categorized into Andean and Mesoamerican gene pools, and 83 significant markers were identified for marker-assisted selection in breeding programs.

Summary: Understanding the link between root morphological traits and yields is crucial for improving crop management. In this study, a pot experiment was conducted to evaluate root traits and grain yield performance of 13 rice cultivars. Considerable variations were observed among cultivars in root traits, total dry matter, and grain yield. Cluster analysis and principal component analysis identified promising cultivars with favorable root traits, total dry matter, and yield performance.

Summary: This study evaluated the main biochemical components, leaf morphological and yield characteristics of 87 elite tea cultivars suitable for black, green, or oolong tea. Significant variations were observed among the tea cultivars as well as seasonal differences in the levels of biochemical components. The natural variation in leaf morphology and yield characteristics was also observed. These findings can be used to establish early selection criteria and enhance tea breeding and production.

Summary: This research aimed to identify RAPD markers associated with morphological traits in pomegranate genotypes. Multiple regression analysis revealed markers showing significant correlations with fruit weight, 100-aril weight, anthocyanin content, and total soluble solids. Some markers were associated with multiple traits, suggesting pleiotropy. These markers can be used to identify genotypes with valuable fruit traits and select suitable parents for mapping purposes.

Summary: This study aimed to confirm the absence of linkage drag in blast resistance genes and analyze their association with yield traits in rice. The results showed that the blast resistance QTL were closely linked with Pi26 and Pi25 genes, and these genes could be used to enhance both blast resistance and grain yield. However, in the Pib and Pita regions, QTL for blast resistance were not found, but QTL for yield traits were detected. Furthermore, several promising QTL clusters for grain weight and size were identified as potential targets for map-based cloning.

Summary: By conducting single-locus and multi-locus genome-wide association studies on a panel of 529 rice core varieties, a total of 152, 106, 12, 111, and 64 SNPs associated with various yield-related traits were detected. Furthermore, 74 significant quantitative trait nucleotides were identified across different multi-locus GWAS methods, and 20 common QTNs were discovered by both single-locus and multi-locus methods. Two candidate key genes (LOC_Os09g02830 and LOC_Os07g31450) were found to affect grain width and thousand-grain weight, respectively.

Summary: The study evaluated the variation and heritability of quantitative and qualitative traits in 60 landrace accessions of noug in Ethiopia. High heritability was found for traits like days to 10% flowering, while traits like number of capitula per plant and number of seeds per capitulum showed medium heritability. However, there was no clear clustering pattern among accessions based on their traits. High oil content accessions showed significant differences in traits related to flowering time, number of seeds per plant, and thousand seed weight. Crossbreeding selected genotypes from the top ranking accessions could lead to the development of new cultivars with early maturity and high seed and oil yields.

Summary: This study aims to investigate the associations among quality variables of papaya fruits and their effects on the selection process. Fruit firmness and soluble solids content show a positive and significant genotypic correlation. Fruit weight and pulp thickness contribute the most to the reduction and increase of pulp volume percentage, respectively. The increase in pulp thickness is correlated with fruit length and pulp volume percentage.

Summary: This study aimed to dissect the quantitative trait loci (QTL) associated with yield components and kernel traits in two wheat cultivars under different environments. The researchers identified 134 QTL regions, including pleiotropic and consistent QTL regions, with three major pleiotropic QTL colocalized with specific genes. Additionally, four consistent QTL were found to explain a significant proportion of phenotypic variation. These findings have implications for marker-assisted selection and QTL map-based cloning in future breeding efforts.
