“…1, 6 and 8 recorded the lowest value of the mean of stability than the mean of the genotypes included in the study, and that the value of α was higher than zero and the significance of α> 0 and λ = 1. This results agrees with (Yadav et al, 2014).…”

“…α does not differ significantly from zero 0 = α and the extent of is not significantly different from one = 1, and this means that this genotype has moderate stability, Genotypes 3, 4 and 5 showed that they have a stability degree above the mean 0> α and λ=1, which means that these genotypes are above average stability and their stability is confirmed and respond even to poor environments, While the genotypes 6, 7, and 8 were less stability than the mean 0 <α and 1 = λ that the values of α were significantly higher than zero and λ=1, this means that these genotypes are less stability than the average of the genotypes included in the study. As for the genotype (2), it was not stable according to (Tai, 1971) because the value of λ =1, this result agreed with what was stated by (Yadav et al, 2014).…”

This research was conducted to estimating the stability of eight new genotypes of flax, which are Sakha 1, Sakha 2, Sakha 3, Sakha 5, Sakha 6, Giza 8, Syrian and Poloni . The genotypes were planted in the research station of the Field Crops Department, College of Agriculture - University of Tikrit during the season (2019/2020), It included six agriculture environments, which are the combination of two planting distances (5 and 10 cm) and three planting dates, and it was applied according to the split-plot system in the Randomized Complete Block Design (RCBD) with three replicates. Plants were distributed in separate plots by four lines for each genotype in each environment, were the length of the line was (2 m) and the distance between the lines was (0.40 m). The main plots contained agricultural environments and the sub plot contained the genotypes. The study included thirteen traits, the duration to 50% flowering and plant height, the number of vegetative branches, and the number of capsules per plant , Number of seeds per capsule, seed yield per plant, The 1000 seed weight, average leaf weight, biological yield, leaf percentage, seed yield, and harvest index. The results showed that the genotypes that occurred in the α area , which were of moderate stability, were (Sakha 2) in the traits of plant height, (Syrian and Sakha 3) in the number of vegetative branches, (Sakha 2 and Sakha 5) in the number of seeds per capsule and (Sakha 1 ,Giza 8) in average the leaves weight and (Sakha 3 and Sakha 1) in the percentage of leaves and (Sakha 5 and Poloni) in the harvest index, The genotypes that are adapted to environments with high productivity were shown as (Sakha 5 and Poloni) in duration to 50% flowering, (Syrian) in plant height, (Giza 8) in the period to maturity, (Sakha 3, Giza 8) in the number of capsules and (Syrian and Sakha 3 and Sakha 1) in The number of seeds per capsule, (Syrian and Sakha 3) in the seed yield of the plant, (Sakha 6) in the weight of 1000 seeds, (Poloni) in the average leaf weight, (Sakha 3) in the biological yield, (Giza 8) in the leaf percentage, and (Syrian and Sakha 6) in the seed yield and (Syrian) in the Harvest index.

A vast area of cultivable lands in saline affected coastal region of South-Western Bangladesh remains fallow during Rabi (winter) season due to non-availability of saline tolerant crop species or varieties. Linseed (Linum usitatissimum) is known as a medium salt tolerant crop with diverse uses. The crop may be a good choice to utilize these saline prone lands. For this purpose a salt tolerant high yielding variety is essential. With this view in mind, a multi-environmental trial of ten linseed genotypes was conducted in saline soils of four locations in this coastal region during Rabi (winter) season of 2020-21, 2021-22 and 2022-23 to identify superior genotypes based on their yield performance, stability and adaptability. The AMMI model ANOVA revealed that the main effects of genotypes (G), environment (E) and GE interaction effects explain 83.95, 1.07 and 12.02% of seed yield variation, respectively. The GE interaction was further subdivided into 9 IPCAs of which first 6 were significant, and the first two IPCAs explained 82.3% of total sum of square where IPCA 1 explained 67.60% and IPCA 2 14.70%. Mean comparison showed that mean seed yield of ten genotypes varied from 625 to 1345 kg ha-1 and that of 12 environments varied from 937-1050 kg h-1 with a grand mean of 1000 kg ha-1. AMMI 1, AMMI 2 and GGE biplot analyses depicted that the highest yielder genotype was G2 followed by G6, G1 and G4. The lowest yielding genotype was G9 followed by G10, G5 and G3. The most stable genotype was G2 followed by G7, G9, G1 and G4, which were widely accepted to almost all environments. The ASV, EV, CV, SIPC and yield index analyses revealed that genotypes G2, G4 and G6 were found to be superior genotypes in seed yield and consistently demonstrating high mean performance across tested environments. Considering the results of biplot analyses and stability parameters like ASV, SIPC, CV, and EV, genotypes G1, G2, G4 and G6 were identified as superior genotypes. The genotypes, G6 exhibited high seed yield, wide adaptation and excellent stable performance over all four tested locations. Thus BD-10698 (G6) can be selected as a variety for cultivation in the saline affected soils of South-Western coastal region of Bangladesh. Genotypes BD-10708 (G2) and Lin-1403 (G4) showed excellent yield performance but medium stability, while Lin-1203 (G9) showed excellent stability but low yield performance. So, BD-10708, Lin-1403 and Lin-1203 can be utilized to develop salt tolerant linseed variety through required breeding program.
