Soybean(Glycine max(L.) Merr.) is a non-native and non-staple crop in sub-Saharan Africa(SSA) with potential to be a commercial crop owing to its wide range of uses as food, feed,and industrial raw material. Soybean was first introduced to SSA by Chinese traders in the19 th century and was cultivated as an economic crop as early as 1903 in South Africa. In the past four decades, soybean cultivation area and production in SSA has increased exponentially, from about 20,000 ha and 13,000 t in the early 1970 s to 1,500,000 ha and2,300,000 t in 2016. Soybean yield has been stagnant in SSA for decades at about 1.1 t ha^(-1),much lower than the world average, representing one of the most challenging issues in the soybean industry in SSA. The low soybean yield in SSA can be attributed to the use of poorperforming varieties and to the limited application of fertilizers and rhizobial inoculants in soils with no history of soybean production. South Africa, Nigeria, Zambia, and Uganda are the leading soybean producers in SSA. Soybean research in SSA is conducted by international and national research institutions, including IITA, national soybean improvement programs, universities, and the private sector. Between 1970 and 2011, 195 soybean varieties were released by IITA, private breeders, and national soybean improvement programs in SSA. This paper reviews the history and current state of soybean production and of the utilization and adoption of tropical varieties in SSA, addresses the major soybean yield-limiting factors across the region, and discusses the potential of the soybean industry in SSA. It also highlights soybean improvement efforts and lessons learned from previous soybean improvement efforts and the current progress of some national soybean improvement programs in SSA. Opportunities for scaling up tropical soybean as a major crop across SSA countries are promising.

Principles and practices of the photo-thermal adaptability improvement in soybean

Journal of Integrative Agriculture 2020年第2期19卷 295-310页

As a short-day(SD)and thermophilic plant,soybean(Glycine max(L.)Merr.)is sensitive to photo-thermal conditions.This characteristic severely limits the cultivation range of a given soybean cultivar and affects the performances of agronomic traits such as yield,plant architectures,and seed quality.Therefore,understanding the mechanism of photo-thermal sensitivity will provide a theoretical basis for soybean improvement.In this review,we introduce the advances in physiological,genetic,and molecular researches in photoperiodism of soybean,and progress in the improvement of the photo-thermal adaptability.We also summarize the photo-thermal conditions and characteristics of widely-planted soybean cultivars of major production regions in China.Furthermore,we proposed a novel concept of‘ecotyping’and the strategies for widely-adapted soybean cultivar breeding.This review provides an important guide for improving the adaptability of soybean.

Micro-tubers are important propagules in potato breeding and potato production, and they are also dormant and easily transported and therefore good targets for mutation induction in potato mutation breeding. A prerequisite for mutation breeding is to determine optimal mutation treatments. Therefore, radio-sensitivity tests of a tetraploid and a diploid potato to gamma irradiation were undertaken. effects of different gamma sources on radio-activity were also studied. In vitro potato cuttings were gamma irradiated using a wide dose range (0, 3, 6, 9, 12, 15 and 20 Gy). The irradiated cuttings were then cultured to induce micro-tubers directly in vitro. Micro-tuber morphotypes were assessed after irradiation of cuttings using three gamma sources with emission activities of 1.8, 7.07 and 139 Gy/min. The diploid species (Solanum verrucosum) was more radio-sensitive than the tetraploid cultivar Desirée (Solanum tuberosum). Gamma dose rates had significant influences on subsequent micro-tuber production at various mutant generations. effects included reductions in the number, size and weight of micro-tubers produced. Gamma dose was more lethal for the diploid potato genotype and micro-tubers produced were small compared to those produced by the tetraploid genotype after irradiation. Different treatments are recommended for diploid and tetraploid potato irradiation in producing large mutant micro-tuber populations. The mutant micro-tuber populations may then be screened for interesting mutations/trait for both genetics and plant breeding purposes.
