In Japan, the selection of short-culm wheat varieties is preferred for breeding purposes to date due to their lodging resistance, whereas culm strength has only marginally improved. However, improving culm strength was suggested to help improve lodging resistance in short-culm varieties. Thus, among the 18 typical and predominant wheat varieties, “Yumechikara” showed maximum bending moment at the breaking of the basal internode and produced the strongest culm. Meanwhile, among other varieties that produced strong culms, some demonstrated considerable bending stress and medium section modulus, whereas some showed medium bending stress and large section modulus. Improved varieties with higher lodging resistance may be produced by crossbreeding of varieties with different levels of culm strength. Regarding the effects of crop management, decreased seeding rates resulted in shorter culm length and increased bending moment at the breaking point of the basal internode, which indicated higher lodging resistance. Therefore, low seeding rates may be suitable for heavily fertilized wheat crops, requiring high lodging resistance.","PeriodicalId":14700,"journal":{"name":"Jarq-japan Agricultural Research Quarterly","volume":"61 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81472850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we developed a new cultivar identification system using the InDel marker. Twelve InDel markers, which revealed clear bi-allelic PCR fragment patterns, were selected from 185 InDel markers. Their primer sets were redesigned to generate less than 650 bp PCR fragments, and all were confirmed to apply to leaf and fresh fruit samples. It was confirmed that they were inherited in a codominant fashion among cultivars with parent–offspring relationships. At least two differentiating InDel polymorphisms to discriminate any paired combination among 33 citrus cultivars were provided, including 14 ancestral varieties and a reference genome cultivar of the clementine mandarin. Minimal marker subsets to identify the target cultivar are listed for each of the 14 registered cultivars with valid breeder’s rights. The developed cultivar identification system features a simple experimental procedure with PCR and electrophoresis, saving time and cost during the inspection process. It could help protect registered cultivars from the illegal distribution of nursery trees and the reimportation of illegal fruits from abroad.","PeriodicalId":14700,"journal":{"name":"Jarq-japan Agricultural Research Quarterly","volume":"108 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85264523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Hokkaido, 98% of the surveyed farms had meadows, 53% had pastures, and 49% had forage crop fields. In all other prefectures, 19% of farms had meadows, 10% had pastures, and 90% had forage crop fields. The median area of each field category per farm was greater in Hokkaido than in the other prefectures. In all places, the application rate of organic fertilizer decreased in the following order: forage crop field > meadow > pasture (37, 8.7, and 2.7 Mg-manure ha −1 y −1 , respectively, in Hokkaido). In forage crop fields, organic fertilizer was applied at lower rates and inorganic fertilizer was applied at higher rates in Hokkaido than elsewhere (37 vs. 69 Mg-manure ha −1 y −1 and 42 vs. 22 kg-N ha −1 y −1 respectively). In meadows, organic fertilizer was applied at lower rates in Hokkaido (8.7 vs. 14 Mg-manure ha −1 y −1 ); however, inorganic fertilizer was applied at similar rates. The annual rate of grassland renovation with full-inversion tillage in 2006-2010 was 3.0% in Hokkaido and 1.3% in the other prefectures. In both regions, manure was intensively applied during grassland renovation.","PeriodicalId":14700,"journal":{"name":"Jarq-japan Agricultural Research Quarterly","volume":"18 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90517582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
