Stability analysis in coriander (Coriandrum sativum L.)

Abstract

Stability studies were performed in 15 coriander genotypes including three checks during rabi 2007-08 to 2009-10. The G × E interaction showed non-significant differential response of the genotypes to the changing environments. Highly significant pooled deviation for all the characters except days to 50 percent flowering, days to maturity and number of umbels per plant and highly significant G × E (Linear) interaction for number of secondary branches and days to maturity indicated the preponderance of non-linear components of G × E interaction. The estimates of mean performance, regression coefficient and deviation from regression for different traits showed that the genotypes RKD 18 and RKD 16 are more stable and can be a useful source for varietal development as these are the widely adapted landraces under common cultivation at farmers’ field in Kota region.
