[Grain-filling characters of different genotype winter wheat under nitrogen fertilization in semi-humid area of south Loess Plateau].

Abstract excerpt

A field experiment was conducted in the south part of Loess Plateau with 632 mm precipitation each year. Three genotypes winter wheat 9430, Xiaoyan No. 6 and Shang188 were used as test materials to study their grain-filling characters under two nitrogen application levels (0 and 90 kg x hm(-2)). The results showed that genetic difference was the main factor affecting grain-filling characteristics, while nitrogen...
