Repeat assessment of CSSL of peanut (introgression of AixAd into cultivated Fleur11) in Lysimeters and LeasyScan, and analysis of the multiyear data

Abstract

Transpiration efficiency (TE) measurements were carried out in a lysimetric system, which has been described in many papers by the group (see Vadez et al., 2014). In short, groundnut plants were grown in 1.2-m length and 20-cm diameter PVC tubes filled with Alfisol, with one plant per tube, with tube arrangement giving a spacing of 20-25 plant m-2. At three weeks after sowing, plant water use monitoring started by regularly weighing the cylinders. Four to eight replicated tubes were used for each genotype-by-treatment combination. Plant water use monitoring took place until maturity, when harvest was done and agronomic parameters were collected.
