Purpose: Panicle architectural traits in rice (branching, rachis length and spikelet number), fixed during the reproductive phase, are strongly variable among genotypes and prone to GxE interaction, i.e. they are highly ...

The qTSN4 was identified as rice QTL (Quantitative Traits Locus) increasing total spikelet number per panicle and flag leaf area but potentially reducing panicle number depending on the environment. So far, this trade-off ...
