Summary: In this study, a genetic linkage map and QTLs related to important agronomic traits in Chinese cabbage were constructed using two diverse inbred lines. The genetic map consisted of 105 SSR markers and spanned 10 linkage groups. A total of 48 QTLs for important agronomic traits were identified. These findings will facilitate further genetic analysis and improvement of Chinese cabbage.

Summary: A population of 352 RILs was generated through the single seed descent method, and 12 QTLs governing yield and yield-related traits were mapped. Among them, a key QTL controlling plant height and panicle length was identified on chromosome 1. These findings contribute to the development of Basmati rice varieties with higher yield through marker-assisted selection.

Summary: This study analyzed a mapping population of wheat derived from 'TAM 113'/'Gallagher' and constructed a high-density genetic map covering all 21 chromosomes. A total of 147 QTLs related to yield and yield-related traits were identified, including consistent QTLs and QTLs with pleiotropic effects. The findings provide valuable information for wheat improvement using marker-assisted selection.

Summary: Maize is a crucial food crop and increasing its yield is a priority for breeding programs. Ear traits, which are quantitatively inherited, play a significant role in maize yield. This study identified and analyzed genetic loci associated with ear traits, refining multiple QTL and QTN clusters. Common intervals detectable by both QTL mapping and GWAS, as well as pleiotropic intervals affecting ear traits, were identified. Additionally, potential candidate genes for improving maize yield were predicted.

Summary: Breeding fruit trees is challenging due to their large trees, long juvenile periods, and environmental variability. The use of molecular markers to assist breeders in selecting genetically superior parents and progeny has been a difficult task. Important fruit traits such as size, weight, sugar and acid content, and ripening time are of interest to fruit breeders.
