dc.description.abstractExperiments were conducted on 70 and 111 F2 plants derived from crosses between PB1 x Palman 579 and PB1 x HKR95-157 respectively and were evaluated for micronutrient content (Fe and Zn) and agronomical parameters. A large deviation was observed for plant height (65-130 and 65-102 cm), effective number of tillers per plant (3-15 and 3-21), panicle length (15.1-27.9 and 15.3-27.9), length/breadth (L/B) ratio (3.73-5.77 and 2.91-4.95), 1000-grain weight (14.08-25.36 and 16.00-26.65 g) (0.033-0.472), yield per plant (1.16-32.96 and 1.1-31.43 g) in F2 populations of PB1 x Palman 579 and PB1 x HKR95-157 respectively. Analysis of micronutrient content including Fe and Zn content revealed that the Fe and Zn content of the three parental rice genotypes namely PB1, Palman 579 and HKR95-157 was 33.6, 16.53 μg/g, 363.53, 22.16 μg/g and 422.13, 17.40 μg/g respectively. The Fe and Zn content among the 70 PB1/Palman 579 F2 plants ranged from 33.80-171.20 and 10.43-31.30 μg/g respectively whereas the micronutrient content in a population comprising of 111 PB1/HKR95-157 F2 plants was 8.63-221.50 μg/g (Fe content) and 3.67-48.80 μg/g (Zn content). An allelic profile was generated for 70 F2 plants of cross PB1×Palman 579 and their parental genotypes to ascertain their aroma trait. Thirty three of the segregants were adjudged aromatic from BAD2 marker analysis. The segregating population was analyzed and enabled us to narrow down certain transgressive segregants with the combination of desirable traits.en_US
