长三角地区黑稻产量、品质与营养成分的品种间差异
Variety variation in yield,quality,and nutritional components of black rice in the Yangtze River delta
摘要
Abstract
To screen high-yield,good-quality and nutrient-rich black rice varieties suitable for cultivation in the Yan-gtze River Delta region,32 black rice varieties(lines)were collected and the differences in their yield,quality and nutrient components were studied.The results showed that black rice varieties(lines)varied significantly in yield,quality,antho-cyanin content,and mineral element content.Specifically,68.75％ of the varieties(lines)had yields ranging from 5 to 7 t·hm-2.All varieties demonstrated brown rice rate that complied with at least the Grade 3 standard(≥77.0％)for quality evaluation,with 50％reaching the Grade 1 standard(≥81.0％).The grain shape of the varieties was mainly of the intermediate type varieties with a length-width ratio of 2.0-2.8.The amylose content varied from 2.47％ to 27.27％,and 59.38％ of the varieties were concentrated within the range of 0-6％.With respect to anthocyanins,the contents of cyanidin-3-O-glucoside and peonidin-3-O-glucoside ranged from 245.86 to 4 477.09 and 21.44 to 367.30 μg·g-1,respectively.The proportion of varieties with anthocyanin content reaching Grade three or above was 90.63％.And among them,the number of varieties with anthocyanin content reaching Grade one only accounted for 34.38％.The content of Ca,Mg and Zn in different black rice varieties(lines)varied from 173.64 to 381.96,1138.55 to 2452.37 and 12.59 to 20.98 μg·g-1,respectively.Correlation analysis revealed that the content of cyanidin-3-O-glucoside and peonidin-3-O-glucoside in black rice were positively correlated with the length-width ratio of brown rice.In contrast,the content of Ca and Mg were negatively correlated with grain thickness,surface area and volume of brown rice.Black rice varieties with a length-width ratio above 2.0 exhibited higher anthocyanin content,while those with lower grain thickness and smaller grain volume showed higher contents of Ca and Mg.In general,a set of elite germplasm resources with high yield,quality and anthocyanin content including Heimi 1-4,Sihei 5,539 17-146-5-1-1,et al.were screened out,which could be promo-ted for commercial production of black rice.关键词
