Abstract

Abstract This chapter focuses on quantitative genetics, screening of germplasm collection at the International Institute of Tropical Agriculture, genetic diversity, genetic variation of provitamin A content in maize. Inheritance, heritability, genotype-by-environment for carotenoid content, population improvement, development of open-pollinated varieties were also discussed. Agronomic performance, stress tolerance, combining ability, heterosis were also conducted in sub-Saharan Africa. It may be concluded that maize in sub-Saharan Africa can be effectively subjected to genetic enhancement of provitamin A, along with other mineral components of the kernel and the plant traits for sustainable, high-quality food sufficiency to drastically reduce hunger and malnutrition.

撒哈拉以南非洲地区维生素a原玉米的数量遗传学、分子技术和农艺性能。
摘要本章主要介绍玉米的数量遗传学、国际热带农业研究所种质资源筛选、玉米的遗传多样性、玉米维生素A原含量的遗传变异。还讨论了类胡萝卜素含量的遗传、遗传力、基因型环境、群体改良和开放授粉品种的开发。在撒哈拉以南非洲进行了农艺性能、抗逆性、配合力、杂种优势等试验。可以得出结论,撒哈拉以南非洲的玉米可以有效地进行维生素原A的遗传增强,以及籽粒中的其他矿物质成分和植物性状,以实现可持续的高质量粮食供应,从而大大减少饥饿和营养不良。
