“…Selama penelitian berlangsung total curah hujan 602 mm. Total curah hujan ini mencukupi kebutuhan air selama pertumbuhan okra yaitu sekitar 584,21 mm (Grillo, 2018). Okra tidak memerlukan curah hujan yang tinggi tetapi jika terlalu kering tanaman memerlukan irigasi (Winch, 2006).…”

IN ULTISOL]. This study aims to determine the dosage of dolomite lime and the type of organic fertilizer that can produce the highest performance of okra plants. This research is an experiment that was compiled based on factorial CRD. The first factor is dolomite dosage, which consists of three levels; 1.11 tons/ha, 1.76 tons/ha, and 2.40 tons/ha. The second factor is the type of organic fertilizer consisting of three types; chicken manure, cow manure, and palm oil solid organic fertilizer. The results showed that the dolomite dose of 2.4 tons/ha produced the highest number of fruits/plants (5.8 fruits) and the heaviest fruit/plant weights (82.1 g). Chicken manure and cow manure produce the highest plant height performance okra (29.8 cm -31.6 cm), the largest stem diameter (72.8 mm -73.8 mm), the highest number of branches (3 stems), the number most fruits / plants (5 -7) and the largest fruit / plant weight (72.4 g -81.4 g). The interaction between dolomite dosage and organic fertilizer did not significantly affect the performance of okra plants.

Soybean is an important agricultural crop known for its high protein and oil content, contributing to essential nutritional and health benefits for humans. Domesticated in China over 5000 years ago, soybean has since adapted to diverse environments and spread worldwide. This study aimed to investigate the genomic characteristics and population structures of 2,317 publicly available soybean whole-genome sequences from diverse geographical regions, including China, Korea, Japan, Europe, North America and South America. We used large-scale whole-genome sequencing data to perform high-resolution analyses to reveal the genetic characteristics of soybean accessions. Soybean accessions from China and Korea exhibited landrace characteristics, indicating higher genetic diversity and adaptation to local environments. On the other hand, soybean accessions from Japan, the European Union, and South America were found to have low genetic diversity due to artificial selection and breeding for agronomic traits. We also identified key variants and genes associated with the ability to adapt to different environments. In Korean soybean accessions, we observed strong selection signals for isoflavone synthesis, an adaptive trait critical for improving soybean adaptability, survival, and reproductive success by mitigating environmental stress. Identifying specific genomic regions showing unique patterns of selective sweeps for genes such as HIDH, CYP73A11, IFS1, and CYP81E11 associated with isoflavone synthesis provided valuable insights into potential adaptation mechanisms. Our research has significantly improved our understanding of soybean diversity at the genetic level. We have identified key genetic variants and genes influencing adaptability, laying the foundation for future advances in genomics-based breeding programs and crop improvement efforts.

Fall Armyworm Tolerance of Maize Parental Lines, Experimental Hybrids, and Commercial Cultivars in Southern Africa

et al. 2022

Fall armyworm [Spodoptera frugiperda (J./E. Smith); FAW] is negatively impacting sustainable maize production, particularly in smallholder farming systems in sub-Saharan Africa. Two sets of germplasm (commercial cultivars and experimental hybrids, and local and exotic inbred lines) were evaluated under managed and natural FAW infestation to identify FAW tolerant material with superior grain yield performance. Significant genotypic effects on foliar FAW damage, ear FAW damage, and grain yield were observed. Commercial cultivars were significantly more affected by FAW infestation than experimental hybrids, as evidenced by high foliar and ear damage scores, yet they out-yielded experimental genotypes. The introduced FAW donor lines (CML338, CML67, CML121, and CML334) showed better tolerance to FAW, individually and in hybrid combinations. Local inbred lines, SV1P, CML491, and CML 539, also showed FAW tolerance. Hybrids and open pollinated varieties were more vulnerable to FAW damage at early growth stages, but they grew out of it through the mid to late whorl stages. Inbred lines showed increasing damage as they grew to maturity. Husk cover, ear rot, anthesis date, and plant height were highly correlated with FAW tolerance. The identified local and exotic lines with FAW tolerance will contribute to FAW resistance breeding in southern Africa.

Rediscovery of Landraces as a Resource for the Future

Abstract: varieties with SSR markers. This finding highlights the urgent need to establish a common procedure, especially for characterizing and preserving landraces, and for supporting its rediscovery and valorization locally.
