【摘要】 花育9812号是山东省花生研究所D141为母本,以D144为父本,采用有性杂交选育而成的花生型品种。粗脂肪平均含量55.11%,蛋白质平均含量27.38%,具有口感细腻,食味好的优质特点。在2013-2014年2a的湖北省区域试验中,花育9812号荚果平均产量5249.85 kg/hm2,籽仁产量为3733.20 kg/hm2,与对照中花15相比,分别增产10.61%和9.86%。2010-201 1年2a中,在山东省花生研究所试验田测产结果,花育9812产量5458.35kg/hm2,较对照鲁花11号、鲁花9号分别增产平均19.03%和11.02%。同时具有稳产、早熟、适应性广、抗倒伏抗逆性强、结果集中适合机械化作业等特点。于2016年6月通过湖北省农作物品种备审定委员会审定(审定编号:鄂审油2016002)更多还原

【Abstract】 Synonymous codon usage biasof coding DNA sequences of proteins in nuclear genome of 24 diploid(A,D genome) and 5 allotetraploid(AD genome) cotton species were analyzed by CodonW program.The results showed that 15 cotton species have similar base composition of codons which possess more pyrimidines(T and C) than purines(A and G) at the third codon position.Relative synonymous codon usage analyses(RSCU) found significant and highly concurrent codon usage bias among the 15 cotton species.Ten high frequency codons were used universally in 28 cotton species.Nc-plot analysis indicated that the RSCU is related to mutation and selection,in which selection plays a leading role.Analysis of the 29 cotton species’ synonymous codon usage biaswould be of great theoretical and practical significance on enhancing the accuracy of the prediction of new genes,and of designing the degenerate primers.更多还原
