Chickpea was phenotyped for time to flowering, carbon isotope composition at peak biomass, and seed weight at maturity in a factorial combining 20 genotypes, 2 sowing dates, 2 sowing regimes over two seasons. 

A field experiment was established on a calcic luvisol at Roseworthy, South Australia (34^o 52' S, 138^o 69'E) that combined factorially 20 genotypes, two water regimes (dry, rainfed; wet, sprinkler irrigated), and two sowing times (early, early June; late, early-mid July). The experiment was repeated twice over successive seasons. Treatments were laid out in a split-split-plot design with three replicates, where sowing time was assigned to the main plot, water regime to the sub-plot, and genotypes randomised within each plot. Each plot comprised 6 rows, 0.24 m appart, 5-m long. We scored phenology weekly to establish the time to 50% of plants at beginning of flowering and calculated thermal time from sowing to flowering using a base temperature of 0 ^oC. To quantify crop water status, we measued carbon isotope composition at peak biomass, shortly after flowering using the method in Journal of Experimental Botany 67: 4339-4351. Seed weight was measured at maturity after drying and threshing 2-m² plant samples.

Missing values: flowering (1 out of 480), seed weight (20 out of 480), carbon isotope (21 out of 480).
