摘 要：
以15个彩色稻品种(系)为试材,对其株高、穗数、穗粒数、结实率、千粒质量、糙米率、精米率、胶稠度以及直链淀粉、可溶性蛋白、维生素C、花青素含量等性状进行比较分析,以期筛选出综合性状比较优良的彩色稻材料.结果表明,参试彩色稻的株高介于92.3~150.0 cm,其中,浙大紫的株高最高,翠玉最矮;穗长介于14.0~30.6 cm,紫香521最长;穗粒数和穗数分别为48.33~178.64粒和5.0~14.6穗,分别以紫香521和绿香米最多;结实率介于45.35%~84.18%,紫香521最高;千粒质量介于15.59~28.01 g,紫红色最高;糙米率和精米率分别为74.02%~83.05%和62.42%~78.60%,黄香米的糙米率和精米率均比较高;垩白度介于0.30%~55.80%,浙大黄的垩白度最小,紫红色最大;碱消值介于2.2~4.8,浙大银最大;胶稠度为72.87~174.93 mm,秦稻2号最大;直链淀粉含量为14.61%~25.73%,其中,翠玉的最高,而黄香米最低;可溶性蛋白含量介于1.43%~1.81%,绿香米最高;维生素C含量介于0.054~0.125 mg/kg,浙大黄最高;花青素含量介于0.030~0.258 mg/g,浙大紫糯最高.利用线性比例变换法对农艺性状和品质性状指标数据进行标准化处理,然后利用加权分析得出不同彩色稻品种(系)的综合排名:浙大紫糯>紫香521>浙大黄>秦稻2号>浙大紫>翠玉>紫金稻>洋黑3号>红香米>紫金黄叶>浙大粉彩禾>绿香米>黄香米>浙大银>紫红色.

摘 要：
Using fifteen pigmented rice varieties(lines) as research materials,their agronomic and quality traits including plant height,panicle number,grain number per panicle,thousand-seed weight,brown and polished rice percentage,gel consistency,as well as the contents of amylose,soluble protein,vitamin C and anthocyanin were analyzed and compared,so as to screen out pigmented rice with excellent comprehensive characters.The results showed that the plant height of pigmented rice ranged from 92.3 cm to 150.0 cm,Zhedazi and Cuiyu had the highest and lowest plant height,respectively;the panicle length ranged from 14.0 cm to 30.6 cm,Zixiang 521 had the longest panicle length;the grain number per panicle and panicle number were 48.33—178.64 and 5.0—14.6,respectively,Zixiang 521 and Lüxiangmi had the highest grain number per panicle and panicle number,respectively;seed setting rate of pigmented rice ranged from 45.35% to 84.18%,Zixiang 521 had the highest value;the thousand-seed weight varied from 15.59 g to 28.01 g,Zihongse had the highest value;the brown and polished rice rates were 74.02%—83.05% and 62.42%—78.60%,respectively,Huangxiangmi had higher brown and polished rice rates;the chalkiness degree ranged from 0.30% to 55.80%,Zhedahuang had the smallest value,Zihongse had the highest value;the alkali digestion value ranged from 2.2 to 4.8,Zhedayin had the highest value; the gel consistency varied from 72.87 cm to 174.93 mm,Qindao No.2 had the highest value;the amylose content ranged from 14.61% to 25.73%,Cuiyu had the highest value,and Huangxiangmi had the lowest value;the soluble protein content ranged from 1.43% to 1.81%,Lüxiangmi had the highest value;the vitamin C content ranged from 0.054 mg/kg to 0.125 mg/kg,Zhedahuang had the highest value; anthocyanin content ranged from 0.030 mg/g to 0.258 mg/g,Zhedazinuo had the highest value.Finally,a linear scaling transformation method was utilized to standardize the data of agronomic and quality traits,and the comprehensive ranking was Zhedazinuo>Zixiang 521>Zhedahuang>Qindao No.2>Zhedazi>Cuiyu>Zijindao>Yanghei No.3>Hongxiangmi>Zijinhuangye>Zhedafencaihe>Lüxiangmi>Huangxiangmi>Zhedayin>Zihongse through weighted analysis.
