Multi-location experiments on maize were conducted from 2016 to 2019 at ten locations distributed across two agro-climatic zones (ACZ) i.e., ACZ-3 and ACZ-8 of Karnataka, India.

- - 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%
With progressive climate change and the associated increase in mean temperature, heat stress tolerance has emerged as one of the key traits in the product profile of the maize breeding pipeline for lowland tropics. The present study aims to identify the genomic regions associated with heat stress tolerance in tropical maize. An association mapping panel, called the heat tolerant association mapping (HTAM) panel, was constituted by involving a total of 543 tropical maize inbred lines from diverse genetic backgrounds, test-crossed and phenotyped across nine locations in South Asia under natural heat stress.
