Abstract:

Combinining features of the best linear unbiased predictions (BLUP) and additive main effects and multiplicative interaction (AMMI) through “Weighted average of absolutescores of best linear unbiased predictions” (WAASB) index in multi-environment experiments may lead to more percise evaluation of genotypes and assessment of genotype × environment interaction. In the present study, the seed yield stability of 14 advanced lentil lines was evaluated in a multi-environment trials in four locations including; Gachsaran, Khorramabad, Moghan and Ilam, Iran in 2018-2019 and 2019-2020 cropping seasons. The experimental design was s randomized complete block design with three replications. Statistical analyzes were performed using multi-environment trials analysis. Considering the significant G×E interaction based on the results of the relative likelihood test (LRT), it was possible to perform BLUP analysis on the data. The highest predicted seed yield by BLUP method belonged to genotype no. 9 followed by genotypes no. 11, 10, 5, which had higher than average predicted seed yield. To enable simultaneous selection based on both seed yield and yield stability, by combining seed yield (Y) and WAASB, a new index “WAASBY” was created. Considering 50% contribution of each of the two components of seed yield and yield stability, eight genotypes showed above average WAASBY. Genoype no. 9 had considerably higher WAASBY when compared with other genotypes and was identified as the best genotype followed by genotypes no. 10, 1, 2, 12, 14, 7 and 13 were ranked respectively. Both control cultivars (genotypes 15 and 16) had lower than average WAASBY. In conclusion, considering WAASBY index, genotypes 9, 10, 1 were identified as genotypes with highe seed yield and yield stability, and can be considered for being released as new lentil cultivars.

Evaluation of Genotype × Environment Interaction and Determining Grain Yield Stability of Durum Wheat Genotypes in Uniform Regional Yield Trials in Semi-Warm Rainfed Areas

There are different methods for study the genotype × environment interactions and determining stable genotypes such as parametric, non-parametric and multivariate methods. In this research, 19 selective genotypes from advanced trials of durum wheat at 2011-2012 agronomic year, have been cultivated with Dehdasht check cultivar for three growing years (2012-2015) in five locations (including Gach...

Evaluation of genotype × environment interaction in durum wheat (Triticum turgidum var. durum L.) regional yield trials

The objective of this experiment was to analyze genotype × environment (GE) interaction for grain yield of 20 durum wheat genotypes to identify the yield stability and adaptability of genotypes using GGE biplot method as well as some univariate stability statistics. The genotypes were evaluated in three rainfed stations of Sararood (Kermanshah), Maragheh and Shirvan, Iran under both rainfed and...

Evaluation of the effect of spatial distribution of weeds on seed yield of lentil (Lens culinaris L.) in rainfed conditions

Weeds are one of the most important factors in reducing yield in legumes crops. Therefore, awareness of the interaction between weeds and crops as well as identification of their spatial variation pattern in the field is important. To investigate the the effect of  weeds on seed yield of lentil, and also to study the spatial distribution pattern of weeds under rainfed conditions, a field experi...
