Abstract
Pasting is one of the most important properties of wheat starch determining the flour quality and functionality. Twenty three New Plant Type (NPT) wheat derivatives along with three checks (PBW 343, HD 2329, and Raj 3765) have been studied in multi-location trials to assess the variation and environment induced fluctuations for their starch pasting properties. Although all flour pasting characteristics varied, Breakdown Viscosity (BV) and Setback Viscosity (SV) exhibited greater variability across environments. Additive Main effects and Multiplicative Interaction (AMMI) analysis indicated significant interactions between Genotypes and Environments Interaction (GEI) in starch pasting properties. Genotypes accounted largest proportion (39.78%) of the Sum of squares (SQ) for peak viscosity (PV) followed by environments (33.30%) and GEI (33.30%). Trough Viscosity (TV), GEI accounted for the largest proportion (40.44%) of the SQ followed by environments (31.76%) and genotypes (27.80%). Genotypes accounted for the largest proportion (44.0%) of the SQ for (BV) followed by environments (33.30%) and GEI (21.59%). With respect to FV, environments accounted for the largest proportion (43.07%) of the SQ followed by GEI (30.84%) and genotypes (26.09%). Environments accounted for the largest proportion (52.48%) of the SQ followed by genotypes (23.89%) and GEI (23.65%) for SV. The interactions between genotype and locations differed greatly; however, some genotypes apparently found to be specifically adaptable to growth location. Correlation among starch pasting characteristics revealed that significant positive correlations were found between PV and BV, FV and TV, as well as SV and FV in all the individual environments tested that can be utilized in selection and simultaneous improvement in for starch quality improvement.

Abstract
This study was conducted to evaluate the performance of forage pea (Pisum sativum spp. arvense L.) genotypes, in terms of fresh forage yield and associated traits, when grown on the Kiziltepe Plain, Mardin, Turkey. Field trials were performed during the 2007-08 and 2009-2010 growing seasons. The experiments were arranged according to randomized block design with three replications. The following trait ranges were reported: Days to 50% flowering: 147.5-162.5 days, Natural plant height and Main Stem Height: 45.58-72.75 cm, Main stem height: 52.52-100.42 cm, Main stem numbers per plant: 1.275-1.658 stems plant-1, Main stem thickness: 2.913-3.703 mm, Fresh forage yield: 10.43-23.83 t ha-1 and Dry matter yield: 2.525-5.891 t ha-1. GGE (i.e., G+GE) biplot analysis showed that the two growing seasons were markedly different,stemming exclusively from differences in rainfall amounts between the two growing seasons. Results of this study showed that the lines 88P00-1-4-9-661 (1) and P101 (6), and cultivar Kirazli (9) were superior in terms of fresh forage yield, dry matter yield, natural plant height and days to 50% flowering traits. At the same time, PC2 scores of these genotypes were found near to zero, so, they were identified as stable genotypes for the investigated traits. In conclusion, in terms of forage yield, these three forage pea genotypes are recommended for the Kiziltepe Plain growing conditions.
