The impact of weeds on rice production is well established, and among PPN, <i>Meloidogyne graminicola</i>, a rice root-knot nematode (RRKN), is becoming a major issue. Although the weeds and RRKN share the same habitat, it is yet unknown how these weeds contribute to the off-season survival of RRKN. Consequently, the current study was done to determine the susceptibility of weeds in the rice wetland ecosystem to RRKN. The weed survey was carried out in rice fields during both crop season and off season, followed by its susceptibility study against RRKN in pot experiment. 24 weed species were discovered to be prevalent including 17 broadleaved weeds (BLW), 5 grassy weeds (GRW) and 2 sedges (SED). Among them the GRW were more frequent (93.33%) and predominant (48.20/0.25 m², 64.71% of all weeds) in the crop season. On the other hand, during the off season, the BLW predominated (55.17/0.25 m², 58.16% of all weeds). Based on our susceptibility test against RRKN, we discovered that, among the 24 weed species, 9 act as good hosts with Build Up Index (BUI) &gt; 10, 4 function as poor hosts with a BUI between 1 and 10, and 11 act as non-hosts with a BUI &lt; 1. We are presenting information on five novel weed species that act as alternate hosts of RRKN for the first time: <i>Macerdonia procumbens, Leptochloa chinensis, Ipomea aquatica, Ammannia baccifera</i> and <i>Eragrostis racemose</i>. The weeds that were observed in both seasons such as <i>Cyanotis axillaris</i> (BUI-16.67), <i>Phyllanthus niruri</i> (BUI-15.97), <i>Macerdonia procumbens</i> (BUI-14.33), <i>Eclipta alba</i> (BUI-14.00), <i>Sphenoclea zeylanica</i> (BUI-13.00) and <i>Echinocloa colona</i> (BUI-15.00) could therefore constitute a serious threat to rice wetland cultivation by assisting the off-season survival of RRKN. The findings underline the importance of weed management strategies in managing the RRKN in rice wetland ecosystem.</p>","PeriodicalId":9841,"journal":{"name":"Cereal Research Communications","volume":"147 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140574005","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}

The present study was carried out in two environments viz., Coimbatore (E1) and Vagarai (E2) to locate QTLs associated with yield-related traits in a recombinant inbred line (RIL) population that resulted from a cross between UMI79 and UMI 936(w). A total of seven yield-related traits (Ear weight, ear diameter, ear length, kernel row number, kernel number per row, 100-kernel weight, and grain yield) were evaluated across the two environments. The QTLs were mapped with the support of genotyping-by-sequencing based SNPs genetic linkage map which contains 1516 markers and spans 10 chromosomes and covers an overall distance of 6924.7 centimorgans. A total of 22 QTLs were discovered across these environments and best linear unbiased predictors, with four of these QTLs being common across them.

This study aimed to investigate the variation in mycorrhizal dependency to <i>Rhizophagus irregularis</i> among five maize varieties from South-Kivu and one from Senegal using a greenhouse experiment. AMF inoculation significantly influenced the intensity of root colonization, growth and physiology of maize varieties, while no change in root colonization frequency was observed. Three of six varieties used responded positively to AMF inoculation. For these varieties, inoculation with <i>R. irregularis</i> significantly improved plant height, stem diameter and SPAD values. The same significant positive trend was observed for maize total shoot and root biomasses (<i>p</i> &lt; 0.05). Significant variation in MD was observed among maize varieties (<i>p</i> = 0.00012) and could be attributed in part to genetic and physiological factors controlling host/fungus compatibility. The non-metric multidimensional scaling (NMDS) analysis discriminated varieties into two main groups, including those with high MD (MD˃5%) and those with low MD (MD &lt; 5%). The analysis of similarity (ANOSIM) for the mycorrhizal inoculation effect index (<i>R</i> = 0.15 and <i>p</i> = 0.0013), suggested high variability for symbiotic traits.

Hence, pot experiment was planned in randomized block design to study the effect of Fe seed priming through different sources, i.e., iron sulfate (FeSO₄.7H₂O), Chelated iron (Fe-EDTA) and nano iron (FeONPs) and their levels on yield and Fe content in direct seeded aerobic rice (variety PR 126) under sandy loam and silt loam soils with three replications.
