Stability analysis of grain yield of lentil genotypes at spring planting in rainfed condition

To study the stability of grain yield in lentil genotypes in spring planting under rainfed condition, 11 genotypes were evaluated in randomized complete block design with four replications at Kermanshah, Maragheh, Zanjan and Ardebil Research Stations during three years (2001-04). The results of combined analysis showed that interaction effects of year * location, and year * location x genotypes were significant. A significant difference was also found among the genotypes at 5% level of probability. Results of stability analysis on grain yield using environmental coefficient variation method indicated that genotypes number 2, 1 and 3 with high yielding and less variation were identified as stable genotypes. Rank Sum of Method (RSM) found genotypes number 3, 5 and 2 were the most stable genotypes. Also results of stability analysis on grain yield using simultaneous selection for yield and stability showed that number 2, 5, 3 were the most stable genotypes. Stability analysis by non-parametric method of rank showed that genotype number 5 was the most stable genotype. Overall based on different stability analysis methods genotypes number 2 (FLIP 82-1L), 5 (FLIP 92-12L) and 3 (FLIP 92-15L) were the most stable genotypes. FLIP 92-12L due to the highest yield is superior to the other genotypes.
