“…It is among major edible oilseed crops grown in Ethiopia, both in terms of acreage and production volume, where 26% of the produce is consumed locally ( Geleta and Ortiz, 2013 ; Ethiopian Institute of Agricultural Research [EIAR], 2017 ). It is also cultivated to some extent in other African countries that include Sudan, Malawi and Uganda ( Geleta and Ortiz, 2013 ; Gebeyehu et al, 2021 ). Apart from Africa, it is cultivated in India as a minor oilseed crop, as well as in Bangladesh, the Caribbean, and the United States, however to a much lesser extent ( Geleta and Ortiz, 2013 ).…”

Genomic resources and tools are essential for improving crops and conserving their genetic resources. Guizotia abyssinica (noug), an outcrossing edible oilseed crop, has highly limited genomic resources. Hence, RNA-Seq based transcriptome sequencing of 30 noug genotypes was performed to generate novel genomic resources and assess their usefulness. The genotypes include self-compatible and self-incompatible types, which differ in maturity time, photoperiod sensitivity, or oil content and quality. RNA-Seq was performed on Illumina HiSeq 2500 platform, and the transcript was reconstructed de novo, resulting in 409,309 unigenes. The unigenes were characterized for simple sequence repeats (SSRs), and served as a reference for single nucleotide polymorphism (SNP) calling. In total, 40,776 SSRs were identified in 35,639 of the 409,309 unigenes. Of these, mono, di, tri, tetra, penta and hexanucleotide repeats accounted for 55.4, 20.8, 21.1, 2.3, 0.2, and 0.2%, respectively. The average G+C content of the unigenes and their SSRs were 40 and 22.1%, respectively. The vast majority of mononucleotide repeat SSRs (97%) were of the A/T type. AG/CT and CCA/TGG were the most frequent di and trinucleotide repeat SSRs. A different number of single nucleotide polymorphism (SNP) loci were discovered in each genotype, of which 1,687 were common to all 30 genotypes and 5,531 to 28 of them. The mean observed heterozygosity of the 5,531 SNPs was 0.22; 19.4% of them had polymorphism information content above 0.30 while 17.2% deviated significantly from Hardy-Weinberg equilibrium (P < 0.05). In both cluster and principal coordinate analyses, the genotypes were grouped into four major clusters. In terms of population structure, the genotypes are best represented by three genetic populations, with significant admixture within each. Genetic similarity between self-compatible genotypes was higher, due to the narrow genetic basis, than that between self-incompatible genotypes. The genotypes that shared desirable characteristics, such as early maturity, and high oil content were found to be genetically diverse, and hence superior cultivars with multiple desirable traits can be developed through crossbreeding. The genomic resources developed in this study are vital for advancing research in noug, such as genetic linkage mapping and genome-wide association studies, which could lead to genomic-led breeding.

Global climate changes taking place over the past decades make the issue of biodiversification of the food supply of our country more and more urgent, which can serve to strengthen it through the introduction of ecologically plastic plants, and, most importantly, resistant to abiotic stresses of the growing season. In this regard, the Abyssinian herb is of interest, in the world it is considered not only as an oilseed, but also as a fodder crop, the green mass of which is suitable for use both fresh and for silage. In 2023, in the agroecological conditions of the Field Experimental Station of the RGAU-MSHA named after K.A. Timiryazev, we conducted a study of nougat in order to determine the possibility of cultivating this crop in the conditions of the Central region of the Russian Federation for fodder purposes. The object of research was the Lipchanin variety, sowing was carried out with a row spacing of 15 cm, without fertilizing in 4-fold repetition.

The Effect of Harvest Date on the Chemical Composition and Fodder Yield of Guizotia abyssinica (Guizotia abyssinica (L.f.) Cass.) under the Climatic Conditions of South-West Poland

Guizotia abyssinica (Guizotia abyssinica (L.f.) Cass.) is regarded as a minor oilseed crop, which is important in terms of its nutritional value and potential uses. An important benefit of this crop is its cultivation for green matter and seed yield even under the difficult conditions of marginal cultivation. Guizotia abyssinica has not yet gained popularity in Europe. However, in a changing climate and taking into account its feeding value, it could gain in importance for ruminant nutrition in the near future. A field experiment was conducted in 2018 and 2019 in the west part of Poland on a farm in Opolskie voivodship (commune Prudnik). The objective of the field study was to assess the effect of three harvest dates on the yield and the chemical composition of fodder in a 90-day cultivation cycle in each year of the study. Stage of growth seems to be the most important factor affecting yield and the chemical composition of Guizotia abyssinica. In both years of the research, the green fodder yield reached the highest value after 90 days from sowing—32.5 and 36.9 t ha−1—while dry matter was 6.85 and 7.99 t ha−1, respectively. Chemical composition was also significantly dependent on harvesting date. Crude protein (in 2018 from 154.5 to 100.7 g kg−1 and in 2019 from 148.3 to 78.2 g kg−1) and crude ash (in 2018 from 165.8 to 98.7 and in 2019 from 155.2 to 89.9 g kg−1) content decreased with progressive harvest date while nitrogen-free extracts (in 2018 from 500.5 to 562.0 g kg−1 and in 2019 from 582.2 to 605.2 g kg−1) and gross energy increased (in 2018 from 19.4 to 21.17 MJ kg−1 and in 2019 from 18.63 to 19.73 MJ kg−1.). The most favorable date for harvesting green forage is 90 days after sowing, due to the significantly highest yield of fresh and dry matter of green forage and with potential as a forage for animals.
