Eleven pigmented rice genotypes were evaluated to estimate genetic parameters, heritability and association. The results indicated that, genotypic variation was high among the lines. The distinct seasonal effect on plant performance for antioxidant capacity, anthocyanin, flavonoids, head rice recovery and test weights was also observed. Wet season favoured the crop performance in all genotypes as compared to drought conditions. The differential accumulation of different quality traits such as AOA, anthocyanin content, flavonoids content, etc showed high heritability, which would be transfer to high yeilding popular rice cultivars through conventional or geneticaly modification techniques. The line Mamihunger was chosen as donor of the high-quality rice grain and Annapurna for high yield. Further, Mamihunger are foreseen to be good in nutritional quality and industry use.
对11个有色稻基因型进行了评估，以估计遗传参数、遗传力和关联性。结果表明，各品系间基因型变异较大。还观察到季节对植物抗氧化能力、花青素、类黄酮、整精米率和容重表现有明显影响。与干旱条件相比，雨季有利于所有基因型的作物表现。不同品质性状如抗坏血酸、花青素含量、类黄酮含量等的差异积累表现出较高的遗传力，可通过常规或基因改造技术转移到高产的普通水稻品种中。选择Mamihunger品系作为优质水稻籽粒的供体，Annapurna作为高产供体。此外，预计Mamihunger在营养品质和工业用途方面表现良好。
