Abstract/ Executive Summary:

Eight genotypes of hull-less barley were evaluated across three locations (Gazipur, Jessore and Ishurdi, Bangladesh) during rabi 2005-06 and 2006-07 to study genotype and environment (G × E) interaction and identify stable genotypes with high yield potential using Eberhart and Russell's model. Eight hull-less barley genotypes (BHL-1, BHL-3, BHL-12, BHL-13, BHL-15, BHL-18, BHL-19 and BB-3) including a check (BB-3) were used as study materials. Results revealed that the means sum squares due to location (L), year (Y), their interaction (L × Y), genotype (G), interactions of genotype, locations and year (G × L), (G × Y), (G × L × Y) were significant for all the characters studied exhibiting considerable variability among the genotypes across locations and years. The combined analysis of variance of genotype (G), environment (E) and their interaction (G × E) also showed strong variability due to environments. According to Eberhart and Russell's model, all of the genotypes were influenced by environment, where, BHL-13 and BHL-18 were mostly responsive to favorable environments; however, BHL-3 and BHl-12 were unpredictable in nature for days to maturity. In respect to plant height, BHL-18 and BB-6 were suitable for poor environment. Among the genotypes, performance of BHL-3 and BHl-12 were unpredictable for number of grains/plant. For 1000-grain weight, BHL-1 was highly responsive to its growing condition, while, BHL-3 seemed to be suitable for poor environment in an unpredictable nature. The remaining genotypes were sensitive to favorable environment. The genotypes BHL-19 had nearly unit regression coefficient (bi) value with small deviation from regression (S2di) value and higher mean of yield/plant in terms of stability indicating that this genotype had stable performance for yield in all the growing environments.

Location: BARI, Gazipur

Start Date: 00-00-2005

End Date: 00-00-2007

Program Area: Variety and Species

Commodity: Barley

Objectives:

To study G × E interaction and to identify high yielding and widely adapted hull-less barley genotypes.

Methodology:

Eight hull-less barley genotypes (BHL-1, BHL-3, BHL-12, BHL-13, BHL-15, BHL-18, BHL-19 and BB-3) including a check (BB-3) were grown at Bangladesh Agricultural Research Institute (BARI), Gazipur; Regional Agricultural Research Station (RARS), Jessore and RARS Ishurdi during rabi 2005-06 and 2006-07. Seeds of each entry were sown in three replications in each location following randomized complete block design. Each plot had five 2.5 m long rows. Plant to plant and row to row distances were 25 and 50 cm, respectively. Urea, TSP and MOP were applied to supply 100, 60, 40 kg of N, P2O5, K2O /ha, respectively. Intercultural operations were done as and when necessary. Data were recorded from ten randomly selected plants from each replication to assess five quantitative characters viz., days to maturity, plant height (cm), number of grains/spike, 1000-grain weight (g) and yield/plant (g). Grain weight was taken at 14% moisture content. Data were analyzed following the method of Eberhart and Russell (1966) as described in Sharma (1998) and Singh and Choudhury (1985).

Achievement/Findings:

BHL-19 had more stable performance with nearly unit bi, very low S2di and higher yield. The genotypes, BHl-1, BHl-13 and BHl-18 had average performance and BHL-12 was suitable for poor environment. Therefore, among the genotypes, BHL-19 with better performance over locations and years was found to be suitable for cultivation in wider range of environmental condition.
