Abstract
Research had been carried out on 190 F
3
plants derived from mineral rich Indica and
elite basmati rice variety. Out of 190, 50 plants were derived from Pusa Basmati 1 x Palman
579 and 140 plants were derived from Pusa Basmati 1 x HKR 95-157 cross. These F
3
plants
were analyzed for mineral content and agronomical traits. A large variation was observed for
plant height (100-168 and 90-163 cm), effective number of tillers per plant (5-19 and 7-30),
panicle length (24.4-34.8 and 20.2-32), length/breadth (L/B) ratio (3.44-6.71 and 3.46-5.81),
1000-grain weight (18.1-30.7 and 11.4-29.6 g), yield per plant (3.9-40 and 8.11-60.12 g) in F
3
populations of Pusa Basmati 1 x Palman 579 and Pusa Basmati1 x HKR 95-157 respectively.
Analysis of micronutrient content including Fe and Zn content revealed that the Fe and Zn
contents in parents Pusa Basmati 1, Palman 579 and HKR 95-157 was 33.6, 16.5 µg/g,
363.53, 22.16 µg/g and 422.13, 17.4 µg/g respectively. The Fe and Zn content among the 50
Pusa Basmati 1 x Palman 579 F
3
plants ranged from 1.2-355.2 and 7.3-112.5 µg/g
respectively whereas the Fe and Zn content in plants derived from 140 Pusa Basmati 1 x HKR
95-157 F
3
plants was 5.8-251.7 µg/g and 8.8-43.4 µg/g. For aroma out of 50 as much as 30
plants were found to be aromatic and out of 140, 94 plants were found to be aromatic in
crosses Pusa Basmati 1 x Palman 579 and Pusa Basmati 1 x HKR 95 157 respectively. The F
3
plants were analyzed to get the plants which have a combination of desirable traits and 20
superior progenies with suitable traits had been selected.
