Table 1.
Mean, range, genetic variance (σ2G), and broad-sense heritability (h2B) estimates for FHB incidence (percentage of infected spikes per plant) and severity (percentage of infected spikelets per spike) in the RIL population derived from crossing FHB-resistant 02-5B-318 and FHB-susceptible cv. Saragolla, evaluated in three environments (Bologna 2012, Bologna 2013, Bari 2013).
