广东烟草种质资源繁种更新试验
2013年春季对83份烟草种质资源进行繁种更新,其中烤烟45份晒烟38份,参试种质完成了主要特征特性的田间鉴定.结果表明：68份种质种子发芽率符合入库要求;参试种质间生育期、形态特征、主要农艺性状等差异较大,生育期变异系数为5.7％～16.9％,依次为移栽至现蕾天数＞移栽至中心花开放天数＞全生育期＞苗龄,全生育期最长为红大11（192.0 d）,最短为江油烟（149.0 d）;主要农艺性状变异系数为6.4％～27.1％,依次为叶数＞节距＞茎叶角度＞株高＞叶宽＞花冠直径＞花萼长度＞叶长＞茎围＞主侧脉夹角＞花冠长度;田间自然发病以普通烟草花叶病（TMV）最严重,青枯病次之,黄瓜花叶病（CMV）、黑...

| Summary: | 2013年春季对83份烟草种质资源进行繁种更新,其中烤烟45份晒烟38份,参试种质完成了主要特征特性的田间鉴定.结果表明：68份种质种子发芽率符合入库要求;参试种质间生育期、形态特征、主要农艺性状等差异较大,生育期变异系数为5.7％～16.9％,依次为移栽至现蕾天数＞移栽至中心花开放天数＞全生育期＞苗龄,全生育期最长为红大11（192.0 d）,最短为江油烟（149.0 d）;主要农艺性状变异系数为6.4％～27.1％,依次为叶数＞节距＞茎叶角度＞株高＞叶宽＞花冠直径＞花萼长度＞叶长＞茎围＞主侧脉夹角＞花冠长度;田间自然发病以普通烟草花叶病（TMV）最严重,青枯病次之,黄瓜花叶病（CMV）、黑胫病、马铃薯Y病（PVY）零星发生,广杂87、黑叶一号、鹤山中南、奀种牛利等种质自然发病率为零. |

The results showed that the germination rate of 68 germplasm was in accordance with the requirements of germplasm bank. Large differences were exsited in the growth period, morphological characteristics and main agricultural characters during the germplasm resources. The CV of growth period was 5.7%-16.9%, arranged from longer to shorter as： the day from transplant to budding, the day from transplant to central flower opening, the whole growth perio |
