The smallholders grow crops for domestic and off‐farm markets, necessitating crop variety attributes for which trait mismatches may limit adoption. Indeed, improved variety adoption is varied and limited, especially for self‐pollinated crops, in part due to the mismatch in characteristics of commercialised varieties. The international research community leads breeding of varieties for under‐invested crops, especially legumes. These varieties are often resilient and productive, but the dynamisms in target agri‐food systems may limit their relevance. Gaining a better understanding of the trait profiles that crop value chain actors consider will increase their adoption. This study combined multi‐location trials and participatory variety selection (PVS) of pigeon pea and groundnut across different environments to evaluate the efficacy of both processes in the breeding of desired varieties. The present study shows improvement in the new materials regarding performance and preference by farmers. Additionally, PVS showed that men prioritised productivity and market‐enhancing traits, whereas women ranked food security traits highest.","PeriodicalId":20228,"journal":{"name":"Plant Breeding","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2023-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46815045","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 structures of the anther cuticle and pollen exine are associated with male sterility. We obtained a completely male sterile mutant (postmeiotic irregular anther1, pia1), which has closed glumes and relatively small and wilted anthers (compared with the wild‐type control). Cytological analysis revealed the normal meiosis and premature tapetal degradation in pia1. Additionally, formation of the pia1 anther cuticle and Ubisch bodies was abnormal, and the pollen exine was discontinuous. Genetic analysis showed that the pia1 mutant was the result of a single recessive mutation of a nuclear gene. On the basis of fine mapping, PIA1 was mapped between the W07051 and W07124 molecular markers on chromosome 1. This region does not contain known genes associated with male sterility. Furthermore, transcriptome analysis indicated genes implicated in transmembrane transport, amino acid transmembrane transport, amino acid transport, and carboxylic acid transmembrane transport are differentially expressed in pia1 mutant anthers. The study findings suggest PIA1 is a novel regulator of anther cuticle and pollen exine development.","PeriodicalId":20228,"journal":{"name":"Plant Breeding","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2023-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49609747","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}

Much of this improvement was made possible through the establishment of and recurring support from the US Wheat & Barley Scab Initiative (USWBSI). Since its inception in 1997, the USWBSI has enabled land‐grant institutions to make advances in reducing the annual threat of devastating FHB epidemics. A coordinated field phenotyping effort for annual germplasm screening has become a staple tool for selection in public and private soft red winter wheat (SRWW) breeding programmes. Dedicated efforts of many SRWW breeders to identify and utilize resistance genes from both native and exotic sources provided a strong foundation for improvement. In recent years, implementation of genomics‐enabled breeding has further accelerated genetic gains in FHB resistance. This article reflects on the improvement of FHB resistance in southern SRWW and contextualizes the monumental progress made by collaborative, persistent, and good old‐fashioned cultivar development.","PeriodicalId":20228,"journal":{"name":"Plant Breeding","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2023-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49003870","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}

However, no studies have focused on starch properties and physical characteristics of low‐amylose buckwheat.

In this study, we bred relatively low‐amylose buckwheat compared to wild type and investigated the causative genes of the traits, starch properties and physical properties of noodles. In the GBSSa mutant, the amylose concentration was lower than that in the wild type. Compared with the wild type, the mutant exhibited the following traits: Amylose concentration decreased by approximately 2%, setback in the Rapid Visco Analyzer decreased by 30 points and the physical characteristics of noodles in the sensory analysis were soft and sticky. These results suggest that this trait may be useful for changing the texture of foods. In addition, the mutant is promising for producing new foods with physical characteristics that are different from those of the wild type.","PeriodicalId":20228,"journal":{"name":"Plant Breeding","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2023-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48370329","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 evaluation of hybrids was conducted in two sets of experiments, including the F2, BC1F1 and F2, F3 generations. The segregation pattern was analysed in the F2 and BC1F1 generations, resulting in a 54:10 ratio of fertile to sterile plants and a 1:1 ratio of fertile to sterile plants, respectively. This indicated the involvement of three genes, at least two of which must be in a dominant condition for restoration to occur, acting in a duplicate complementary manner. In the F3 generation, both crosses were grown to confirm the stability of restorers, and they segregated in the ratio of 10 true‐breeding families and 44 segregating families, which was consistent with the F2 ratio. Additionally, this study observed the influence of rainfall on the partial restoration pattern over seasons, as restorer genes are up or down‐regulated depending on the availability of water.","PeriodicalId":20228,"journal":{"name":"Plant Breeding","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2023-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45305139","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 aims of this study were thus to investigate the relationship between resistance against multiple Fusarium species and to assess the potential of an indirect phenotypic and genomic selection for the resistance against the accumulation of several mycotoxins in wheat. Strong phenotypic and genetic correlations between the mycotoxin contents, FHB severity and FHB‐associated traits were observed, irrespective of if traits were assessed in trials inoculated with a DON or HT‐2/T‐2 producing Fusarium species. A multi‐stage phenotypic or genomic selection with low anther retention being used for an indirect selection among early generation selection candidates, followed by an evaluation of the pre‐selected set in disease nurseries, and lastly by assessing the mycotoxin content of the most promising genotypes is suggested as a suitable strategy to breed for wheat cultivars with reduced risk of mycotoxin accumulation.","PeriodicalId":20228,"journal":{"name":"Plant Breeding","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49358970","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}
