Genotype × Environment Interactions and Stability Analysis for Grain Iron and Zinc Concentrations in Rice (Oryza sativa L.) Genotypes
International Journal of Current Microbiology and Applied Sciences
Micronutrient enrichment in the major staple food crops is an important breeding goal in view of the extensive problem of 'hidden hunger' caused by micronutrient malnutrition. Grain iron (Fe) and zinc (Zn) concentrations were evaluated in a set of 37diverse rice genotypes during rainy (kharif) season of 2013. Based on the performance of the entries across the locations, highly promising for kernel Fe concentration among genotypes studied, the genotypes RPHP 106, RPHP 114, RPHP 134 and RPHP 135
... P 134 and RPHP 135 were considered stable as they recorded high mean (μ) with regression coefficient (b i ) near 'unity' and non-significant deviation from regression (S²d i ). Similarly, for kernel Zn concentration among the genotypes studied, the genotypes RPHP 81, RPHP 84, RPHP 103 and RPHP 157 were considered stable as they recorded high mean (μ) with unit regression coefficient (b i ) and non-significant deviation from regression (S²d i ) and considered as stable based on Eberhart and Russell (1966) stability criteria.
