中文摘要:
      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曰参试种质间生育期、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跃移栽至中心花开放天数跃全生育 期跃苗龄,全生育期最长为红大11(192.0 d),最短为江油烟(149.0 d)曰主要农艺性状变异系数为6.4%~27.1%, 依次为叶数跃节距跃茎叶角度跃株高跃叶宽跃花冠直径跃花萼长度跃叶长跃茎围跃主侧脉夹角跃花冠长度曰田间自然发 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。
英文摘要:
      Propagating and regeneration for 83 tobacco germplasm resources was counducted in the spring of 2013, including 45 flue-cured tobacco and 38 air-cured tobacco, and the main characteristics of field identification were completed. 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 period, seedling age. 耶Hongda 11爷had the longest whole growth period (192.0 days), and 耶Jiangyou tobacco爷had the shortest whole growth period (149.0 days). The CV of main agricultural characters was 6.4%-27.1%, arranged in the following order: leaf number, node interval, angle between stem and leaf, plant height, leaf width, corolla diameter, calyx length, leaf length, stem girth, angle between main vein and lateral veins, corolla length. Tobacco mosaic virus (TMV) was the most serious of natural infection in field, followed by bacterial wilt, cucumber mosaic virus (CMV), black shank, potato virus Y (PVY) sporadically occurred. The natural incidence rates of 耶Guangza 87爷, 耶Black leaf No.1爷, 耶Heshan Zhongnan爷, 耶Enzhong Niuli爷were zero.
