When the 189 ILs were evaluated under drought stress and
normal irrigated conditions of Hainan during the 2011–2012 DS,
water treatments (T) had highly significant effect on all
measured traits, but this variation component varied considerably
among different traits with R2 ranging from 2.3% for PN to
45.7% for FNP. On average, the yield reduction caused by the
drought stress was 20% for HHZ (the recipient) but 36.1% for the
189 ILs.
