and rainy seasons 2006. Results of the summer season grain analysis showed significant differences among the S 1
progenies of ICTP 8203 and CGP. The remaining two populations (GGP Bulk and PVGGP 6) are yet to be
analyzed. Approximately two-fold variation was observed for both grain Fe and Zn content in both ICTP 8203
(55.3−138.2 mg kg -1 Fe and 38.9−106.7 mg kg -1 Zn) and CGP (64.4−150.7 mg kg -1 Fe and 57.9−99.6 mg kg -1 Zn)
(Figs. 3 and 4). Nine progenies of ICTP 8203 and 23 of CGP population had grain Fe content in excess of 100 mg
kg -1 (100.3−150.7 mg kg -1 ); and 10 progenies in each of the two populations had grain Zn content in excess of 80
mg kg -1 (80.5−106.7 mg kg -1 ). There was highly significant (P70 mg kg -1 Fe and >50 mg kg -1
Zn identified (KNR/RB/KLS, 2009)
Stability of grain Fe and Zn content: Twenty-eight entries representing a wide range of Fe and Zn content and
selected from a 120-entries trial conducted for two seasons along with a check OPV (WC-C 75) were further
evaluated during the summer and rainy season of 2005 and the summer season of 2006 for stability of these
micronutrients. Grain Fe and Zn data from these five trials were subjected to stability analysis following Eberhart
and Russell model. Highly significant (P
