“…For instance, a rice line with submergence tolerance and best cooking quality (also called ideotype 1, ID1) exhibited a low-amylose content, a fragrance and a high alkali spreading value [113]. The best preferred rice plant also has the following properties: low tillering capacity (3-4 productive tillers), 200-250 grains per panicle, very sturdy stems, erect leaves, and high harvest index [114].…”

“…Breeding tools such as marker-assisted selection were efficient to create the ideotype of choice. For instance, a rice line with submergence tolerance and best cooking quality (also called ideotype 1, ID1) was developed using this method [220]. In addition to being tolerant to waterlogging and having jasmine-like cooking quality, ID1 lines exhibited a low-amylose content, a fragrance and a high alkali spreading value.…”

Abstract:The Green Revolution has enabled Asian countries to boost their crop production enormously. However, Africa has not benefitted from this agricultural revolution since it did not consider local, but important crops grown in the continent. In addition to their versatile adaptation to extreme environmental conditions, African indigenous crops provide income for subsistence farmers and serve as staple food for the vast majority of low-income consumers. These crops, which are composed of cereals, legumes, vegetables and root crops, are commonly known as underutilized or orphan crops. Recently, some of these under-researched crops have received the attention of the national and international research community, and modern improvement techniques including diverse genetic and genomic tools have been applied in order to boost their productivity. The major bottlenecks affecting the productivity of these crops are unimproved genetic traits such as low yield and poor nutritional status and environmental factors such as drought, weeds and pests. Hence, an agricultural revolution is needed to increase food production of these under-researched crops in order to feed the ever-increasing population in Africa. Here, we present both the benefits and drawbacks of major African crops, the efforts being made to improve them, and suggestions for some future directions.

“…MAS is a combination of traditional genetics and molecular biology and allows for the selection of genes that control traits of interest. Combined with traditional selection techniques, MAS has emerged as a valuable tool for selecting organisms with interesting traits during crop breeding (Stendal et al, 2006;Chen et al, 2010;Kumar et al, 2010;Jantaboon et al, 2011).…”

ABSTRACT. Maize (Zea mays L.) is one of the most important cereal crops worldwide, and increasing the grain yield and biomass has been among the most important goals of maize production. The plant architecture can determine the grain yield and biomass to some extent; however, the genetic basis of the link between the plant architecture and grain yield/biomass is unclear. In this study, an immortal F 9 recombinant inbred line population, derived from the cross Mo17 x Huangzao4, was used to detect quantitative trait loci (QTLs) for 3 traits associated with plant architecture under two nitrogen regimes: plant height, ear height, and leaf number. As a result, 8 and 10 QTLs were identified under the high nitrogen regime and low nitrogen regime, respectively. These QTLs mapped to chromosomes 1 (six QTLs), 2 (one QTL), 3 (one QTL), 7 (two QTLs), and 9 (eight QTLs), and had different genetic distances to their closest markers, ranging from 0 to 22.0 cM, explaining 4.7 to 20.5% of the phenotypic variance. Because of an additive effect, 9 and 9 could make the phenotypic values of traits increase and decrease to some extent, respectively. These results are beneficial for understanding the genetic basis of agronomic traits associated with plant architecture and for performing marker-assisted selection in maize breeding programs.
