<p>This study aimed to clarify the effects of nitrogen topdressing timing and application rate on grain yield and grain protein content in ‘Hokkai 266’, a successor line to the winter wheat cultivar for bread ‘Yumechikara’. Field trials were conducted in Memuro in 2021 (sown in 2020) and in Bihoro in 2022 (sown in 2021). Nitrogen topdressing treatments were designed by varying the allocation of fertilizer applied at the regrowth, spike formation, and flag leaf stages. ‘Hokkai 266’ produced more than 100 additional spikes m<sup>–</sup>² compared with ‘Yumechikara’ at both sites and tended to show higher grain yield. Grain protein content increased significantly in treatments where topdressing at the regrowth stage was omitted or reduced and fertilizer allocation at the flag leaf stage was increased, compared with the control. Although no significant correlation was detected between grain yield and grain protein content, ‘Hokkai 266’ exhibited a strong negative correlation between spike number and grain protein content, suggesting that the increase in spike number is associated with reduced protein content. Furthermore, grain weight tended to decline in upper spikelets and in the second and third florets depending on fertilizer allocation. These findings suggest that the yield and protein content in ‘Hokkai 266’ may be increased by reducing nitrogen application at the regrowth stage and emphasizing topdressing at the flag leaf stage while avoiding excessive spike production.</p>

<p>Ukraine, blessed with fertile black soil and a steppe climate, has supported the world’s food supply as Europe’s leading wheat producer. Ukrainian genetic resources are also extremely important for Japanese wheat breeding. A prime example is ‘Yumechikara,’ a bread wheat developed in 2009 and currently the most widely cultivated bread-making variety in Japan. This variety was developed by crossing the US line ‘KS831957’ with Hokkaido lines ‘Satsukei 159’ and ‘Kitanokaori.’ The Ukrainian parent of ‘KS831957,’ ‘Odesskaya 51,’ contributed resistance to wheat yellow mosaic disease and excellent baking quality. Additionally, ‘Turkey Red,’ a Ukrainian variety introduced to North America in the 19th century, contributed to the development of Japan’s ‘Nōrin 10’ and major Hokkaido varieties. Ukrainian wheat breeding began in the late 19th century under Imperial Russia and produced excellent varieties like ‘Mironovskaya 808’ during the Soviet era. However, the political regimes significantly impacted development, causing research stagnation due to Lysenkoism and the tragedy of the Holodomor. Since independence, the National Academy of Agrarian Sciences has led research, continuing to develop varieties combining cold tolerance, drought resistance, and high quality. However, the war since 2022 has markedly reduced production, with research institutions also suffering damage. Amid the ongoing war and climate change, the bond in wheat breeding connecting Ukraine and Japan offers important insights for envisioning a sustainable future for food production.</p>

<p>Wheat yellow mosaic (WYM) disease, caused by the wheat yellow mosaic virus (WYMV), significantly affects wheat production. Three WYMV pathotypes—I, II, and III—have been identified in Japan, each with a distinct geographical distribution and pathogenicity. To investigate the historical and geographical distribution of infection-resistant wheat varieties in Japan and the relevant genetics, we comprehensively evaluated the response to WYMV pathotypes and the genotypes conferring resistance in accessions of the Japanese wheat core collection. In the experimental fields harboring WYMV, most of the varieties that showed stable resistance were breeders lines; only a few were traditional varieties. Resistant accessions are particularly prevalent in northern Japan. These results suggest that resistant varieties have been developed through modern breeding, in which crossbreeding with foreign varieties has played a major role. Resistance-conferring genes on the chromosome 2DL and 5AL appeared to have been introduced during this breeding process, and the 5AL locus became widely distributed in Japanese varieties. Through genome-wide association studies, we identified a novel resistance-conferring locus on chromosome 7AS. Furthermore, the resistant haplotype on 7AS confers robust resistance to pathotype I when combined with the haplotype carried on 5AL. The results of this study contribute to the understanding of resistance-associated genetics in the context of WYM disease, highlighting the potential of particular genomes to confer robust and durable resistance in breeding efforts.</p>

<p>Soybean production in northern Kyushu (Saga and Fukuoka Prefectures), Japan, has declined since 2008. As major cultivar and cultivation management have hardly changed in recent years, this decrease should be caused by climate variability. Thus, we evaluated the variability of the recent climate in northern Kyushu and its impact on soybean production. Trend analyses and the Lepage tests were conducted on air temperature, solar radiation, and precipitation over the past 30 years. The correlations between these meteorological conditions and soybean yield were assessed. Solar radiation from late August to early September, corresponding to the soybean flowering stage, declined since 2008 and showed a strong positive correlation with yield, suggesting a critical limiting factor. Shifting the flowering stage through early or late sowing could mitigate this effect. Precipitation during the growing season was negatively correlated with soybean yield, indicating that improvements in drainage management are effective. Interestingly, soybean yields remained high under low precipitation conditions, showing that soil drought did not significantly limit production. These findings highlight the need for adaptive strategies, including adjustments of sowing date and improved water management, to enhance soybean production in northern Kyushu.</p>
