investigating the impact of generation on the growth and yield of pea (𝑃𝑖𝑠𝑢𝑚 𝑆𝑎𝑡𝑖𝑣𝑢𝑚 𝐿.)

Considering the nutritional value of pea (pisum sativum l.) and its seed generations in crop yield, this study was conducted to investigate the effects of various generations of pea on yield and yield components in the gorgan region of iran. the treatments included three generations: f1, f2, and f3. planting was carried out with a row spacing of 33 cm and an intra-row distance of 10 cm. this experiment was designed as a randomized complete block design with three replications. sampling occurred during the flowering, green pod, and ripening stages. the following traits were measured: the number of plants with red flowers, leaf area index, stem height, number of pods per plant, weight of green pods, number of seeds per pod, weight of one hundred grains, dry biomass weight, yield of green pods, seed yield, and the harvest index. the data were analyzed using excel and sas software. based on the findings of this study, it can be concluded that the green pod yield and several other traits measured in the second generation of pea did not exhibit a statistically significant difference compared to the first generation; any observed differences were minimal. however, the use of seeds from the third generation resulted in a significant decrease in yield (3,088.99 kg/ha, 2,873.71 kg/ha, and 2,095.44 kg/ha in the f1, f2, and f3 generations, respectively.) and yield components when compared to both the first and second generations. it was concluded that uilizing second-generation pea seeds from the wolf variety can help reduce planting costs while achieving the desired yield of green pods.
