Nutrient Content for Newly Improved Breeding Rice Lines from Parentage of the Kavuni and CO 50

The objective of the study was determining the physical properties and minerals composition in the twenty three breeding lines and two parent rice varieties. Physical properties found that no significant difference in terms of shape and size of the grain. The calcium, iron and zinc content of rice samples in the ranged from 7.56 to12.72 mg/100g, 0.73 to 2 mg/100g and 2.29 to 3.39 mg/100g, respectively. Results showed that the cultures 144-5 (12.72 mg/100g)>155-3(12.62 mg/100g)>144-2(12.61 mg/100g) =148-2 (12.61 mg/100g) contained higher levels of calcium content. Among the rice lines accessions, the samples: 144-2 (2.04 mg/100g)>32-2 (2 mg/100g)>145-2 (1.67 mg/100g)>145-3 (1.57mg/100g) had higher contents of iron. The zinc content of rice lines ranked in the following decreasing order; 144, 144-1,144-2, 144-3, 145-3, 145-6, 143-1,148-2,271-2. From the twenty three rice lines, some of the rice lines contained more minerals than of parent kavuni. The finding indicated that the cross breeding technique may increases not only the yield and also nutrient content of rice.
