- * Metabolomics is a valuable research tool that analyzes the metabolic changes in maize when affected by FAW, helping identify specific metabolites that play a role in the plant's defense.
- * The review emphasizes the potential of using metabolomics data to inform pest management strategies and develop maize varieties that are more resistant to FAW, while also calling for more integrated research methods to improve global food security.
Combining ability status of the inbred lines is crucial information for hybrid breeding program. Diallel or line × tester mating designs are frequently used to evaluate the combining ability. In the current study a modified diallel model was used, wherein the Griffing's combining ability effects were further partitioned to understand the effects due to maternal and reciprocal.

- - The study analyzes genetic trends in maize breeding pipelines at CIMMYT across eastern/southern Africa, South Asia, and Latin America, using data from over 4,000 trials and 34,000 entries conducted globally over the last decade.
- - Genetic improvements in grain yield were significant, with increases recorded at rates of 138 kg/ha/year in Eastern/Southern Africa, 118 kg/ha/year in South Asia, and 143 kg/ha/year in Latin America.
- - The research indicates that success in genetic improvement is linked to the use of new breeding technologies, effective phenotyping networks, and stable funding, exemplified by the Eastern Africa Product Profile 1a pipeline achieving a 2.46%
High oleate peanuts have two marketable benefits, health benefits to consumers and extended shelf life of peanut products. Two mutant alleles present on linkage group a09 (ahFAD2A) and b09 (ahFAD2B) control composition of three major fatty acids, oleic, linoleic and palmitic acids which together determine peanut oil quality. In conventional breeding, selection for fatty acid composition is delayed to advanced generations.

Leaf rust, caused by Puccinia arachidis Speg, is one of the major devastating diseases in peanut (Arachis hypogaea L.).
