图4 qTBN5-NILs的基因型和表型效应 a: 雄穗分枝数主效基因qTBN5的定位; b: qTBN5-NILs的基因型, 白色为郑58背景, 黑色部分为来自昌7-2的qTBN5基因所在片段; c: 雄穗分枝数; d: 株高; e: 穗位高; f: 抽雄期; g: 雄穗主轴长。**表示在 0.01水平差异显著, ns表示差异不显著。

Fig. 4 Genotypes and phenotypes of qTBN5-NILs a: physical locus of qTBN5 identified in RILs population. b: genotypes of qTBN5-NILs. Black part is segment from Chang 7-2 indicating gene position and white parts are genetic background from Zheng 58. c: tassel branch number. d: plant height. e: ear height. f: days to pollen. g: total tassel length. Error bars represent SD. “**” and“ns” show significance at P<0.01 level and on significant difference, respectively as determined by t-test.
