Underpinning regions associated with nitrogen use efficiency in Brassica juncea L. Czern: using associative transcriptomics approach.

ABSTRACT:

Background

Breeding crops for enhanced understanding of apparent nitrogen use efficiency (NUE) requires understanding of phenotypic variations and underlying genetics. Improving NUE in Indian mustard is considered important to reduce nitrogen (N) fertilizer use without sacrificing crop yield. In the present study, 260 genotypes of Brassica juncea were field evaluated for seed yield and NUE-related traits at three N levels: N₀ (no added nitrogen), N₅₀ (50 kg/ha nitrogen), and N₁₀₀ (100 kg/ha nitrogen) for two years.

Results

N response in plants varied depending on the dose of nitrogen applied and tended to vary across genotypes and the plant's developmental stages. A pooled analysis of variance revealed significant variations in the diversity-
