| dc.description.abstract | Genotype x location interactions as well as stability for plant height, maturity and pod yield were determined in twenty five peanut genotypes across three different agroclimatic areas of Bangladesh. For stability analysis, the procedure outlined by Finlay and Wilkinson (1963) and Ebcrhart and Russell (1966) were followed. The genotypes, locations and the genotype x location interactions were differed significantly for all the traits. The linear and non-linear portion of the G x L interaction were also found significant. From the estimated stability parameters it was observed that most of the early maturing genotypes were unpredictable due to significant deviation from regression (S2di>0). Overall, the line 2408/1 was found suitable for favorable environment and the line ICG (FDRS)-36 and NCAC-17090 for unfavorable environment. The lines ICG(FDRS)- 01, ICG(FDRS)-10, ICG (FDRS)-23, ICG(FDRS)-33, CS-26 and J-ll having above average yield performance with moderate plant height and maturity were identified as stable genotypes with wide adaptability. Among these, only the line ICG (FDRS)-23 was found stable for all the three traits with wide adaptability. | en_US |
