摘　　要：彩色稻米蕴藏的营养价值、健康效益和市场经济价值正不断吸引着国内外水稻育种工作者和稻米消费者的兴趣。以龙锦1号/香软米1578高世代重组自交系群体223个家系为试验材料,测定糙米花色苷含量、千粒重、穗粒数等11个指标,并进行变异分析、方差分析、相关分析、主成分分析、聚类分析和差异显著性分析,筛选出优异色稻新品系和高花色苷水稻新品系。结果表明,糙米花色苷含量为2.30~12 011.04 mg/kg,平均值为594.91 mg/kg。糙米粒色等级与千粒重、糙米粒宽、糙米粒厚呈显著负相关,与糙米花色苷含量呈极显著正相关。家系42的综合排名最高,其余依次为家系96、152、99、186,这5个优异色稻家系的糙米花色苷含量为20.74~12 011.04 mg/kg。高亲龙锦1号的糙米花色苷含量为4489.36 mg/kg,有8个家系的糙米花色苷含量显著增加,其中家系152、186的糙米花色苷含量分别为12 011.04、8421.58 mg/kg,两者既属于优异家系又属于高花色苷家系,为创制的优异高花色苷水稻新种质。The nutritional value,health benefits and market economic value embedded in pigmented rice are continuously attracting the interest of rice breeders and rice consumers both domestically and internationally.A total of 223 family lines from the Longjin 1/Xiangruanmi 1578 high-generation recombinant inbred population were used as test materials,and 11 indexes such as anthocyanin content in unpolished rice,1000-grain weight,and grains per panicle were determined and subjected to variation analysis,variance analysis,correlation analysis,principal component analysis,cluster analysis,and significance analysis of differences,in order to screen superior colored rice new cultivars and new high-anthocyanin cultivars.The results showed that the unpolished rice anthocyanin content was 2.30-12011.04 mg/kg,the mean value was 594.91 mg/kg.Grain color grade of unpolished rice was significantly negatively correlated with 1000-grain weight,grain width,and grain thickness of unpolished rice,and were highly significantly positively correlated with anthocyanin content of unpolished rice.Family line 42 had the highest comprehensive ranking,followed by family lines 96,152,99,and 186,and the unpolished rice anthocyanin content of these five superior colored rice families ranged from 20.74 to 12011.04 mg/kg.The anthocyanin content of the high parent Longjin 1 was 4489.36 mg/kg,and there were eight families with significantly increased anthocyanin content(P<0.05),among which the anthocyanin content of families 152 and 186 were 12011.04 and 8421.58 mg/kg respectively.Lines 152 and 186 belonged to both an excellent family and a high anthocyanin family,and were new excellent high anthocyanin rice germplasm created.
