Isolation and expression analysis of the HvnAnt2 gene in qingke barley (Hordeum vulgare L. var. nudum Hook. f.) varieties with different grain coloursOriginal Paper

To investigate the role of the HvnAnt2 gene in the formation of different qingke barley grain colours, HvnAnt2 was isolated from the leaves of the White 91-97-3 (white), Blue qingke (blue), Kunlun 17 (black), and Purple qingke (purple). The HvnAnt2 gene encodes a hydrophilic unstable protein consisting of 561 amino acids, without a transmembrane structure and without a signal peptide, with one bHLH-MYC_N and one HLH domain at amino acids 22–204 and 387–436, respectively. The HvnAnt2 of qingke barley was most closely related to Hordeum vulgare and most distantly related to Triticum monococcum; it was mainly...

QTL mapping for heading date and plant height using a RIL population in rice in different photoperiod environmentsOriginal Paper

Hong-Wei Zhang, Ling-Zhi Wang, Ying Xie, Liu-Gen Hao, Zhen-Zhen Wang, Chong-Fen Yi, Hui Guo, Yu Gan, Guan-Lun Xiang, Zhi-Qiang Yan, Ze Song, Zhan-Lie Yang

Czech J. Genet. Plant Breed., 2024, 60(3):119-125 | DOI: 10.17221/2/2024-CJGPB

Heading date determines rice seasonal and regional adaptation, while plant height is an important trait related to rice lodging resistance. In this study, a recombinant inbred line population was used to detect quantitative trait loci (QTLs) for both traits in long-day (LD) and short-day (SD) environments. Three and two QTLs for heading date were detected in LD and SD environments, respectively. Notably, qHD8 and qHD10 were commonly detected in both environments. Five and four QTLs for plant height were identified in LD and SD environments, respectively. Among them, qPH3, qPH5 and qPH6 showed no pleiotropic effects...

Exploring potato diversity: A comprehensive genetic and phenotypic analysis of quantitative and qualitative traitsOriginal Paper

Tasnim Khandaker Samiha, Md Ataur Rahman, Saiful Islam, Nusrat Jalal, Aparna Islam, Abu Shamim Mohammad Nahiyan

Czech J. Genet. Plant Breed., 2024, 60(3):126-135 | DOI: 10.17221/10/2024-CJGPB

For sustainable breeding in potato, a better understanding of genetic diversity within germplasm banks for sustainable breeding is needed. This study comprehensively characterised the molecular and phenotypic traits of 62 potato accessions, including advanced clones and indigenous potato varieties from Advanced Chemical Industries Limited (ACI Ltd.), Bangladesh, and 8 varieties from the Bangladesh Agricultural Research Institute (BARI). By using 9 SSR markers and 13 morphological traits, including both quantitative and qualitative traits, we observed correlation coefficients ranging from –0.3 to 0.7 for 8 quantitative traits, and Pearson's chi-square...

Molecular basis of differential sensitivity to MeJA in floret opening between indica and japonica riceOriginal Paper

Zhiqiang Yan^, Ruyue Deng, Huihui Tang, Hongwei Zhang, Susong Zhu^

Czech J. Genet. Plant Breed., 2024, 60(3):136-148 | DOI: 10.17221/43/2024-CJGPB

Methyl jasmonate (MeJA) accelerated floret opening in rice, crucial for addressing inconsistent floret opening in hybrid seed production of indica × japonica hybrids. However, indica and japonica rice exhibited notable differences in their sensitivity to MeJA’s impact on floret opening, with indica responding faster. To clarify the molecular basis of MeJA-induced floret opening sensitivity differences between indica and japonica rice, after 1 h of MeJA spraying, transcriptomes and endogenous floret opening regulators were compared between indica and japonica rice, with histology differences observed. The results showed that MeJA quickly activated...

Evaluation of Levante × Karakılçık durum wheat advanced lines for yield related and quality traits using principal component biplot analysisOriginal Paper

İmren Çöken Tekin, Ali Tekin, Ziya Dumlupınar

Czech J. Genet. Plant Breed., 2024, 60(3):149-157 | DOI: 10.17221/18/2024-CJGPB

The Karakılçık landrace is known for its quality traits, especially protein content. However, its high plant height causes lodging and yield loss, which limits the production area. A Levante × Karakılçık population developed by crossing the local Karakılçık wheat with the commercial variety Levante in order to eliminate the disadvantages of Karakılçık and adapt it to wider production areas. In the study, yield, quality, and some physiological traits were investigated in the population. The experiment was conducted in an augmented experimental design in the cropping seasons of 2021–2022 and 2022–2023....
