Forage Pea Pure Lines: Winter Hardiness, High Seed and Biological Yield

Öz

Winter forage pea is a plant that grows in cold climates and is a valuable source of protein for animal feed. In this study, 13 pure forage pea lines (PS3057M1, PS3057M2, PS3073G1, PS3073G2, PS3073G3, PS4028H1, PS4028H2, PS4028H3, PS4028H4, PS4053M1, PS4053M2, PS4053M3 and PS4053M4) and Emirbey and Şahin varieties were used as material. The research was conducted at Selçuk University Prof. Dr. Abdülkadir AKCİN Research and Application Station in the trial fields during the 2020-21 and 2021-22 plant growth periods without irrigation. The trials were established in both years according to randomized block design with 3 replications. Meteorological data indicated that despite variations in the lowest temperatures between the two years, all pea lines remained undamaged. This highlighted the adaptability of forage pea lines to the region's winter conditions, which is consistent with previous studies. Statistically significant differences were determined between the two years of the study in terms of all traits analyzed in the research. Higher values were recorded in the second year for all traits. The main reason for these differences is the precipitation and temperatures in the spring months, which is the period when the plants grow actively. Again, significant statistical differences were determined between the lines in all the traits analyzed in the study. This shows us that genetic traits and environmental conditions are important in determining the traits analyzed in this study. The forage pea lines used in the study performed better than the standard varieties in terms of seed and biological yield. In conclusion, this research shows that newly developed winter forage pea lines can be successfully grown in the Konya region and these lines have important genetic and environmental effects on various yield parameters.
