Limited commercial quality protein maize (QPM) varieties with low grain yield potential are currently grown in Eastern and Southern Africa (ESA). This study was conducted to (i) assess the performance of single-cross QPM hybrids that were developed from elite inbred lines using line-by-tester mating design and (ii) estimate the general (GCA) and specific (SCA) combining ability of the QPM inbred lines for grain yield, agronomic and protein quality traits. One hundred and six testcrosses and four checks were evaluated across six environments in ESA during 2015 and 2016.

Genetic gain estimation in a breeding program provides an opportunity to monitor breeding efficiency and genetic progress over a specific period. The present study was conducted to (i) assess the genetic gains in grain yield of the early maturing maize hybrids developed by the International Maize and Wheat Improvement Center (CIMMYT) Southern African breeding program during the period 2000-2018 and (ii) identify key agronomic traits contributing to the yield gains under various management conditions. Seventy-two early maturing hybrids developed by CIMMYT and three commercial checks were assessed under stress and non-stress conditions across 68 environments in seven eastern and southern African countries through the regional on-station trials.

Article Synopsis
  • - 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%

Background: Person-centered maternity care is respectful and responsive care to individual women's preferences, needs, and values and ensuring that their values guide all clinical decisions during childbirth. It is recognized as a key dimension of the quality of maternity care that increases client satisfaction and institutional delivery. However, little research has been conducted about person-centered maternity care in Ethiopia.
