分析了49份黑稻品种的加工、外观、蒸煮与食味营养品质及谷粒特征等性状间的遗传相关和遗传通径,结果表明:黑米的蛋白质、色素、P、Fe,Zn 和 Mn 的含量等6个营养品质性状分别与密度、粒长、长宽比表现正相关,与粒重、体积、粒宽及直链淀粉含量表现负相关,其中与密度和长宽比的相关多数达到了显著水平。因此,在黑稻品种选育中,选择粒形中等且细长、籽粒密度偏高的材料,利于改善品质性状。 The genetic correlations and genetic pathways of processing, appearance, cooking and eating nutritional quality and grain characteristics of 49 black rice cultivars were analyzed. The results showed that the protein, pigment, P, Fe, Zn and Mn of black rice Content and other six nutritional quality traits were positively correlated with density, grain length, aspect ratio, negative correlation with grain weight, volume, grain width and amylose content, of which the correlation with the density and aspect ratio reached the majority Significant level. Therefore, in the breeding of black rice varieties, selection of medium grain size and slender, high grain density of materials, help to improve the quality traits.
