为了有效地利用甜高粱种质资源,促进育种工作,采用田间调查和室内考种分析相结合的方法,对黑龙江省的194份甜高粱种质资源群体的农艺性状进行了分类鉴定和评价.结果表明:大部分资源的生育期集中在116~160 d ;株型性状均差异较大;单穗粒重主要集中在21~60 g ,但差异极大,极差为110.0 g ,千粒重平均23.1 g ,极差为19.4 g ;茎秆含糖量平均为13.3%,集中分布在13.1%~15.0%,含糖量高的资源较少;单株重平均为379.5 g ,主要集中在200~500 g ,极差较大,为640 g ,单株重大于600 g 的资源共有10份.通过充分了解这些资源的特异优良农艺性状表现,可为今后有目的地利用这些甜高粱种质资源进行品种改良提供理论依据.

In order to utilize germplasm resources effectively for breeding ,194 sweet sorghum accessions of Heilongjiang province were evaluated and classified based on investigation results to agronomic characters in field and indoor .The re‐sults showed that growth period of most sweet sorghum accessions ranged from 116 to 160 d ;Characters related with plant types had great difference among the varieties ;Although the grain weight per spike mainly varied between 21 g and 60 g ,but the range reached 110 g ;The average weight per 1 000 grains was 23 .1 g and its range was 19 .4 g ;The percent‐age of average sugar content in stem was 13 .3% ,mainly varied between 13 .1% and 15 .0% .A few sweet sorghum acces‐sions contained more sugar .The average individual plant weight was 379 .5 g ,mainly varied between 200 g and 500 g ,and its range was 640 g .There were 10 sweet sorghum accessions whose individual plant weight greater than 600 g .By fully observing the performance of specific good agronomic characters of those resources ,it could provide the theoretical basis for improving sweet sorghum varieties in future .
