Abstract

Biochemical analyses were carried in an effort to assess the superior quality of rice seeds. Seeds of thirteen rice cultivars IR64 MR84 MR151 MR159 MR167 analyzed for strach and protien content. In addition ascorbic acid content and glutathione reductase GR activity were also determined for their antioxidative properties. The dry weight of seeds was recorded. The results obtained showed that seeds of cultivar RU 2242-1-1 contained the highest strach content 34.06 mg/g fr.wtfollowed by MR209 26.21 mg/g fr.wt and IR 64 24.07 mg/g. The seeds with low strach content are MR207 18.11 mg MR159 18.48 mg/g and Setanjung 18.73 mg/g. The level of strach present in the seeds may indicate the photosynthetic and strach synthesis efficiency of the cultivars. Seeds of MR221 exhibited the highest protien content 147.77 ug/g fr.wt followed by MR84 141.59 ug/g fr.wt and MR159 100.52 ug/g fr.wt while seeds of cultivars MR207 26.63 ug/g fr.wt MR167 33.55 gu/g fr.wt and Setanjung 37.39 ug/g fr.wt have low protien content.
