| 摘 要： | 利用携带光周期迟钝基因 (Photoperiod1简称Ppd1)的 6套近等基因系分别与其背景亲本AVALON ,BRIGAND ,BRIMSTONE ,MERCIA ,NORMAN及RENDZVOUS相比较 ,研究该基因在石家庄地区生态条件下对冬小麦农艺性状的影响。结果表明 ,该基因提早冬小麦抽穗、开花及成熟 ,缩短生育期 ;缩短穗长 ,使旗叶变短、变窄 ,面积变小 ;增加分蘖成穗率 ,每穗沟数 ,穗粒数及千粒重。因此认为该基因对石家庄地区生态条件下的小麦高产且早熟育种中利用价值很大 |

| Abstract: | The effect of photoperiod insensitive gene Ppd1 on characteristics of winter wheat were studied in Shijiazhuang winter wheat environments,by using 6 sets of near isogenic lines respectively in 6 genetic background of AVALON,BRIGAND,BRIMSTONE,MERCIA,NORMAN and RENDZVOUS.The result showed that the gene could make winter wheat to be earlier date of heading,flowering and maturing and could shorten growing period.Both spikes and flag leaf were shortened by the gene Ppd1.The flag leaves of the lines with Ppd1 gene become narrow and their leaf areas become smaller comparing with the background varieties.In addition,Ppd1 gene could increase spike rate of tillers,grain number per spike and tiller,and 1000 grain weight. |
