In addition, varieties with superior germination and growth at low temperatures are required for direct sowing, which enables the low-cost production of rice. We developed Akikei770, a near-isogenic line from the high-quality, good-tasting cultivar Akitakomachi, carrying the <i>qLTG3-1</i> gene from the Maratelli cultivar, which enhances low-temperature germinability. Although Akikei770 exhibited improved low-temperature germinability, it was inferior to Akitakomachi in appearance quality of brown rice and in eating quality of cooked rice. In Akikei770, a short arm region of up to 222 kb on chromosome 3 from Maratelli was introgressed, and only the <i>qLTG3-1</i> gene exhibited polymorphisms within the coding region compared to Akitakomachi. The <i>qLTG3-1</i> genotype was significantly associated with brown rice quality in the F₂ population, which indicates that the <i>qLTG3-1</i> gene was involved in this trait with no involvement of other chromosomal regions of Akikei770. The functional <i>qLTG3-1</i> allele in Akikei770, encoding a hybrid glycine-rich protein (HyGRP) that is localized on the cell wall or membrane, enhanced the low-temperature germinability. Because a loss-of-function allele of <i>qLTG3-1</i> increased the appearance quality of brown rice in a recessive manner, it was concluded that HyGRP, which enhances low-temperature germinability, has a pleiotropic effect that reduces the appearance quality of brown rice.</p>","PeriodicalId":11803,"journal":{"name":"Euphytica","volume":"145 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141866415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to estimate the effects of selfing on fruit traits in S₁ and S₂ inbred families of guava and to explore potential impacts on genetic diversity. Eighteen S₁ families were generated through selfing of progenies from biparental crosses, and ten S₂ families were produced by selfing superior genotypes from S₁ families. The experiment was conducted at the Experimental Station of Ilha Barra do Pomba, in the municipality of Itaocara-Rio de Janeiro, Brazil. It utilized a randomized complete block design, with three replications and ten plants per plot. Evaluated traits included fruit weight, length, diameter, length-diameter ratio, endocarp thickness, mesocarp thickness, pulp weight, and soluble solids content. The data underwent individual analysis of variance, yielding predicted mean trait values for S₁ and S₂ generations, alongside correlation and homozygosity estimates. Genetic diversity was assessed using Mahalanobis distance and UPGMA cluster analysis, and comparative box plots between inbred populations were created for the evaluated traits. Box plot analysis revealed symmetry in most evaluated traits, suggesting uniformity in the data due to the selfing strategy. Analysis of variance indicated statistically significant differences in all traits, highlighting variability between populations S₁ and S₂. Fruit and pulp weights exhibited high homozygosity levels, with values of 90.86 and 102.59 respectively, linked to increased fruit traits in the S₂ population, indicating their importance in the fixation of favorable alleles. Fruit weight, length, and diameter, endocarp thickness, and mesocarp thickness showed strong correlations, exceeding 0.70. Genetic diversity assessment via Mahalanobis distance indicated a decrease in genetic variability, evidenced by fewer groups in S₂ compared to the S₁ population. However, this reduction did not noticeably affect the average performance of the S₂ population. The results indicate that the two generations of self-pollination did not negatively affect the phenotypic values of the evaluated traits.</p>","PeriodicalId":11803,"journal":{"name":"Euphytica","volume":"30 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141866307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The genotypes chosen included canola cultivars, our newly developed WOSR breeding lines, yellow-seeded, semi-resynthesized and mutant genotypes, together with ogu-INRA F1 hybrids and their parental lines.

The average SY in six environments varied from 16.55 to 41.64 dt·ha⁻¹. The AMMI analysis showed significant effects of both G and E, as well as GEI, for the above traits.

Across the RTB crops, the key quality and adoption criteria differ for different products. The vital quality traits that can enhance the adoption of these improved varieties have been identified for cassava, yam, and banana/plantain. Some significant traits cassava farmers and consumers prefer are early-bulking, non-bitter roots, in-ground storability, drought tolerance, good pounding capabilities, and excellent cooking and sensory qualities. The acceptance of improved yam varieties is driven by good yield, resistance to pests, good cooking quality, and admirable textural attributes for both boiled and pounded yams.

Farmers’ and end-users’ most desired traits are high yields, good cooking qualities, and climate resilience.

This crop is primarily grown for the high concentration of galactomannan gum that is present in the seed endosperm, and it can improve ecosystem services by fixing atmospheric nitrogen. However, the genetics of guar nodulation remains poorly understood. Therefore, the objective of this study was to assess the variation of nodule and plant growth traits in a set of guar germplasm. A total of 225 United States Department of Agriculture (USDA) guar accessions were evaluated for nodule traits in three runs of a greenhouse pot study. Results showed that all traits except fresh plant biomass varied significantly among genotypes (p-values &lt; 0.05). Broad-sense heritability was high for nodule diameter, nodule weight per plant, and plant biomass production, indicating that genetic gain in these traits can be attained through the plant breeding process. This is promising, since selection for high values in these traits would be expected to increase nitrogen fixation and yield. There were strong and significant positive correlations between nodule number and both fresh and dry nodule weights (<i>r</i> = 0.79 and 0.71, respectively), as well as dry plant biomass and dry nodule weight (<i>r</i> = 0.8), indicating that greater plant growth is associated with increased nodule weight. Many genotypes were found to perform better than checks included in this study, which may be useful in guar breeding initiatives. PI288747 is top performing accession for all traits except nodule diameter which can be a good parent for breeding program.
