The nutritional composition of taro was accessed to select nutritional-rich genotypes using, additive main-effects and multiplicative interactions (AMMI), weighted average absolute scores (WAAS), best linear unbiased prediction (BLUP), genotype plus genotype × environment interaction (GGE) biplots, and multi-trait selection index (MTSI). The AMMI1 and AMMI2 biplots identified 11CE, 1CE, and 13CE as stable genotypes. 13CE, 8CE, and 24CE are stable as per the WAAS biplot. Which-won-where/what model highlighted 24CE and 26CE as winners in E1, E3, and E4 environments. The genotypes, 16CE, 24CE, 10CE, 25CE, 10CE, 18CE, 22CE, 26CE, 1CE, and 14CE, have recorded high predicted BLUP for sugar (2.36 %), starch (60.81 %), protein (19.24 g/100 g), P (424.23 mg/100 g), K (1197.41 mg/100 g), Fe (17.89 mg/100 g), Cu (1.53 mg/100 g), Zn (13.78 mg/100 g), Mn (6.67 mg/100 g), and yield (12.04 t/ha), respectively. 13CE, 15CE, 7CE, and 8CE are selected based on MTSI values. Overall, 24CE, 8CE, 13CE, and 16CE are stable for nutritional contents.

Induction by caterpillars of stored and emitted volatiles in terpene chemotypes from populations of wild cotton (Gossypium hirsutum).

Background: Upland cotton (Gossypium hirsutum) plants constitutively store volatile terpenes in their leaves, which are steadily emitted at low levels. Herbivory leads to a greater release of these stored volatiles. Additionally, damaged plants increase the accumulation of volatile terpenes in their leaves and begin to synthesize and emit other terpenes and additional compounds.

Smallholder wheat farmers of Ethiopia frequently use landraces as seed sources that are low yielders and susceptible to diseases due to shortage of seeds of adapted improved bread wheat varieties. Developing novel improved varieties with wider adaptability and stability is necessary to maximize the productivity of bread wheat. Hence, a multi-location field trial was conducted across four locations in south Ethiopia during the 2022/23 main cropping season with the objective of estimating the magnitude of genotype by environment interaction (GEI) effect, and determine the stable genotype among the 10 Ethiopian bread wheat advanced selections using a randomized complete block design (RCBD) with three replications.

African swine fever (ASF) is a highly contagious disease affecting wild and domestic pigs, characterised by severe haemorrhagic symptoms and high mortality rates. Originally confined to Sub-Saharan Africa, ASF virus genotype II has spread to Europe since 2014, mainly affecting Eastern Europe, and progressing through wild boar migrations and human action. In January 2022, the first case of ASF, due to genotype II, was reported in North-western Italy, in a wild boar carcass.
