英文摘要	Biofortification of pearl millet (Pennisetum glaucum (L.) R. Br.) with improved iron (Fe) and zinc (Zn) will have great impact as it is an indispensable component of nutritional security of inhabitants of arid and semi-arid regions. Ten genotypes along with checks were evaluated in RBD in six locations during kharif, 2016 under rainfed conditions. Significant differences were observed in genotype, environment and genotype x environment interaction mean squares for grain Fe and Zn contents, indicating differential nutrient accumulation by the genotypes. The first two principal components obtained in AMMI analysis were significant and cumulatively explained the total variation were 81.47 % for Fe and 73.97 % for Zn. A positive and moderately high correlation (r=0.6) between Fe and Zn contents suggests good prospects of simultaneous improvement for both micronutrients. Among the ten genotypes, PPMI 953 was found to be more stable with high mean Fe (90 ppm) and Zn (59 ppm) contents. On crossing with designated A lines of pearl millet, the line PPMI 953 found to be restorer for A(l) system with complete fertility restoration of F-1 panicle of the cross, ICMA((1)) 863 x PPMI 953 under bagged condition and resulting F-1 with 78-84% fertility measured by seed setting % under bag. The F-2 individuals showed 9:7 fertility-sterility ratio (chi(2) value=0.002, P value=0.964). The promising line, PPMI 953 may be used as source for further genetic improvement with respect to grain micronutrient content or can be directly used as male parent in development of high iron pearl millet hybrlds.
