Clonal variation in apical dominance of Triplochiton scleroxglon K. Schum, in response to decapitation por Ladipo, D.O., Leakey, R.R.B., Grace, J.

“…Responses to decapitation can thus be used as a robust indicator of genetic variation in apical dominance, provided care is taken: (i) to avoid extreme environmental conditions; and (ii) to maintain uniformity in the morphological (height, no. of leaves etc.) and physiological state (eg water and nutrient status) of the plants and their growing environment (especially light).…”

Nutrient-dense orange-fleshed sweetpotato: advances in drought-tolerance breeding and understanding of management practices for sustainable next-generation cropping systems in Sub-... por Low, Jan W., Ortíz, R., Vandamme, Elke, Andrade, M.I., Temesgen, B.B., Grüneberg, W.J.

“…In the future, HEBS will be combined with greater use of modern genomic tools, new phenotyping tools, and CRISPR/Cas9-mediated gene editing. Second, beyond genetic enhancements, evidence is presented that using improved crop management systems, existing sweetpotato yields can be increased 2–4 times. …”

Breeding implications of nodulation performance and root structure under natural inoculation for soil fertility enhancement and sustainable cowpea production por Mekonnen, T.W., Hailemariam, F.M., Amsalu, B., Gedil, Melaku A, Labuschagne, Maryke T.

“…However, clusters II and V recorded the minimum inter-cluster distance (78.96 units). The range of intra-cluster distance was 24.22–5,112.92 units, indicating that the high genetic distance displayed within and between clusters has to be exploited via crossing and selecting the most divergent parents for future cowpea improvement. …”
