DOI: 10.1080/02571862.2016.1213323
Abstract: Ascertaining the relationship of genetic diversity and combining ability would aid the design of a breeding strategy for maize hybrids. Twelve tropical maize inbreds were crossed in a half-diallel to study gene action for yield… read more here.

DOI: 10.1371/journal.pone.0211623
Abstract: The circadian clock regulates numerous biological processes in plants, especially development and stress responses. CIRCADIAN CLOCK-ASSOCIATED 1 (CCA1) is one of the core components of the day–night rhythm response and is reportedly associated with ambient… read more here.

DOI: 10.1590/1678-992x-2016-0079
Abstract: The development of efficient and low-cost genotyping methods is essential to precise genetic characterization of cultivars. Here, we present a system based on fluorescently labeled universal tail sequence primers (UTSP) to resolve microsatellite (SSR) markers… read more here.

DOI: 10.3389/fpls.2021.685488
Abstract: In maize, doubled haploid (DH) line production capacity of large-sized maize breeding programs often exceeds the capacity to phenotypically evaluate the complete set of testcross candidates in multi-location trials. The ability to partially select DH… read more here.
