The evaluation and computation of yield stability of a genotype over environments is a critical component of a certain breeding program. The present study was intended to screen 11 advance chickpea (Cicer arietinum L.) genotypes and one check for genotype × environment interaction (G × E) at six locations with varying micro and macro climatic conditions for yield correlated phenotypic characters. A number of 11 advanced genotypes of chickpea and one check variety were assessed for their adaptability at six different locations of Bangladesh. The randomized complete block design (RCBD) with three replications was chosen to experiment. The means were used to compute Additive Main Effects and Multiplicative Interaction (AMMI) analysis of variance, followed by regression analysis to measure × E. The regression analysis showed significant genotype × environment interaction for all the phenotypic characters. The mean values of days to flowering, days to maturity, plant height, number of po...

Elite lines of kabuli chickpea developed through mutation breeding at Nuclear Institute for Agriculture and Biology (NIAB), Faisalabad were evaluated for stability of grain yield at four diverse locations in the Punjab province during 2003-04, 2004-05 and 2005-06. The genotype yield, regression coefficient (bi), deviations from regression (S 2 d) with sustainability index was used to identify the stable genotypes. Analysis of variance showed highly significant differences for environment (location, year), genotype and their interactions. Genotype x environment interaction (G x E) was of crossover in type. Mean seed yield performance in 12 environments indicated the superiority of mutant CM256/99 which produced the highest seed yield of 1349 kg ha -1 followed by CM305/99 (1344 kg ha -1 ). The CM256/99 and CM305/99 were having non-significant high bi and S 2 d values coupled with high sustainability index. This showed that both mutants were better responsive to the favorable environme...

A field experiment was conducted during Rabi, 2019-20 at Sehore, Madhya Pradesh to investigate the association of yield and its related components of physiological traits in Chickpea under three sown environments. Seed yield per plant was showed significant positive association with LA & LAI at 60 days after sowing in E-I, CGR in E-III. This suggested that attributes might be utilized primarily for selection of high yielding genotypes, with yield contributing characters potentially playing a key role as selection parameters for isolating a high yield in eligible genotypes.

This study was carried out to determine the productive responses of 10 chickpeas (Cicer arietinum L.) genotypes to different places and years. Hasanbey, Aksu, Seckin, Damla 89, Gulumser, Cagatay, Sezenbey, Inci, Gokce and Uzunlu 99 chickpea genotypes were used as plant material. This research was conducted in Yozgat, Kirikkale and Kirsehir Provinces of Turkey in 2014, 2015 and 2016. The experimental design was a randomized block with 4 replicates. Environmental variance, variation coefficient, ecovalance, stability variance, superiority measure, regression coefficient, deviation from regression and coefficient of determination methods were used for stability calculations. Aksu genotype had the highest stability level, whereas Seckin, Damla 89 and Uzunlu 99 chickpea genotypes also successfully grown with respect to stability parameters. Cagatay chickpea genotype showed the highest yield potential, if grown in ideal environmental conditions. To conclude, the ideal yield would be obtained in the event that the requirements of if the genotypes are fulfilled by desired environmental conditions.
