The Species Catalogue of China:Volume 1:Plants (SCCP) is a new,comprehensive,hardcopy inventory of Chinese higher plants that combines several datasets and references to recent taxonomic treatments.The database,with all attached additional information,is freely accessible via the internet (http://www.sp2000.org.cn/)and on CD-ROM,and will be updated yearly.It includes bryophytes (157 families,599 genera,and 3167 specific and infraspecific taxa),lycophytes and ferns (41 families,181 genera,and 2336 specific and infraspecific taxa),gymnosperms(10 families,45 genera,and 311 specific and infraspecific taxa),and angiosperms (270 families,3227 genera,and 35873 specific and infraspecific taxa);in total 478 families,4052 genera,and 41687 specific and infraspecific taxa.Several other important statistics can also be drawn from the database,such as the distribution pattern of the four major groups of higher plants,as well as number of endemic and naturalized or cultivated genera/taxa.Entries in SCCP are also compared with Flora of China,and Flora reipublicae popularis Sinicae at the genus level.The SCCP will not only be a useful reference for floristic or biodiversity studies in China,but will also serve as a key resource to direct action and monitor progress.It is intended to be a useful resource for achieving Target 1 of the Global Strategy for Plant Conservation (GSPC).

为充分利用地方花生种质资源,扩充花生遗传育种亲本库,对“第三次全国农作物种质资源普查与收集行动”中收集到的134份江西地方花生种质资源的9个主要农艺性状运用变异分析、相关性分析、主成分分析和聚类分析对其进行鉴定评价,并筛选出特异种质.结果 表明,单株生产力的变异系数最大,为49.13%,其次,总分枝数、主茎高、百果重和百仁重的变异系数也较高,生育期和出仁率的变异系数较小;相关性分析表明单株生产力与总分枝数、生育期呈极显著正相关,可适当增加总分枝数,以提高单株产量;主成分分析将9个主要农艺性状归为3个主成分

玉米粗缩病是我国玉米种植区主要的病毒病害,发掘优异的抗性种质资源和选育优良抗病品种是防治玉米粗缩病最为经济有效的措施.本研究在粗缩病重病区采用田间自然发病方法,对201份玉米种质资源进行了连续2年的抗性鉴定和评价,同时采用人工接种方法对其中25份种质开展了进一步的鉴定.结果 表明,仅沈137高抗粗缩病;P138、丹3130、辽68、齐318、黄野四、CA339、H191、齐319、X178、SH15、金黄59、R18等12份自交系表现抗病,835、中自01、9046、多黄29、CA335、金黄96B、海9
大豆是重要的植物油脂和蛋白来源,干旱是限制大豆生长发育及产量的重要因素之一.为研究大豆不同生育时期对干旱胁迫的反应,综合评价大豆种质资源抗旱性,筛选抗旱优异种质,本研究在大豆芽期、苗期和全生育期分别采用改进后的抗旱性鉴定方法对253份种质资源进行鉴定,测定根长、株高、百粒重等形态指标,计算发芽率、反复干旱存活率、加权抗旱系数等评价指标,通过相关分析和回归分析筛选抗旱性评价指标,进行大豆种质资源抗旱性综合评价.结果 表明,干旱胁迫后,测量指标值降低幅度较大(10.27%~96.62%),与正常灌水处理呈极显
