Fig. 5From: Genome‑wide identification and expression analysis of the UBC gene family in wheat (Triticum aestivum L.)Association analysis of TKW, KL, KW and KT between two haplotypes of TaUBC25 gene in three environments. A The mean thousand grain weight of TaUBC25 haplotypes in the modern cultivars. B The mean kernel length of TaUBC25 haplotypes in the modern cultivars. C The mean kernel width of TaUBC25 haplotypes in the modern cultivars. D The mean kernel thickness of TaUBC25 haplotypes in the modern cultivars. The X-axis represents different environments (Luoyang, 2002; Luoyang, 2005; Shunyi, 2010). The values show the mean ± SE (n > 50 grains). Significant statistical analysis was carried out by Student’s t-test (*, P < 0.05; **, P < 0.01)Back to article page
