Abstract:

To screen out buckwheat varieties suitable for planting in Zhejiang Province and their appropriate planting altitude and sowing period, four tartary buckwheat varieties and four common buckwheat varieties were introduced in 2023 for comparative experiments at different sites to study the growth and agronomic traits. The results showed that high altitude and late sowing date were conducive to the improvement of buckwheat yield; the tartary buckwheat variety Zhongku 3 had low plant height, the agronomic traits were moderate, the average yield was the highest, and it was suitable for large-scale planting; and the common buckwheat variety Zhongqiao 21 had high yield and was safflower buckwheat, which was suitable for promotion and application as an ornamental and grain variety.

Key words: Buckwheat, Introduction, Growth period, Yield
