Loop-design (triangle design with the comparison of each triplet: hybrid + parent 1 and parent 2) and pairwise design (hybrid + parent 1, hybrid + parent 2) were used in the experiment.
Four inbred lines and their four inter-pool hybrids were hybridized respectively in two-colour chips experiments.
The objective of our study was to:(i) identify differentially expressed genes in relation to heterosis for plant height, (ii) relate gene expression patterns to the dominance and overdominance hypothesis, (iii) determine the consistency of expression patterns between inbred parent - hybrid triplets also in view of differing degrees of relatedness of triplets, and to (iv) validate consistently differentially expressed genes between hybrids and their parental inbreds by real-time (qRT) PCR.
