a NF in Hubei Province, b NF in Henan Province, c NFI in Hubei Province, and d NFI in Henan Province. The data represent the average values over 3 years (2015–2017). Vertical bars indicate standard deviation (n = 9). Means within each variety that share the same letter are not significantly different according to the LSD test (0.05).
