“…After cooling, the solutions were kept in plastic bottles until analysis by spectrophotometer. Fructose was determined by spectrophotometer using periodate reaction (Saengkanuk et al, 2011). Inulin content was based on fructose measurement, ignoring trace amounts of glucose and reducing free fructose, glucose, and sucrose.…”

Drought is a major problem for Jerusalem artichoke production in rainfed areas, as it reduces inulin accumulation in tubers (Conde et al., 1991;Schittenhelm, 1999;Monti et al., 2005). Under rainfed conditions, drought greatly reduced stalk dry weight, tuber dry weight, sugar yield, and inulin yield of Jerusalem artichoke, and differential responses of Jerusalem artichoke genotypes to drought for these characters were observed (Kocsis et al., 2007(Kocsis et al., , 2008. A supply of 50% of the water requirement reduced tuber yield by 20% (Conde et al., 1991) and 22.8% (Losavio et al., 1997). Among inulin-containing and sugar-containing crops, Jerusalem artichoke is more susceptible to water stress than sugar beet or root chicory (Schittenhelm, 1999).

Genetic variations in germplasm and genotype 9 environment interaction (G 9 E) are important for crop improvement. The objectives were to explore genetic variation in Jerusalem artichoke germplasm and to evaluate G 9 E interaction for inulin content. Seventy-nine accessions of Jerusalem artichoke were evaluated in a randomized complete block design with two replications for three seasons. Significant variation in inulin content (55.3-74.0% dry weight) was observed and the genotypes with high inulin content could be identified although there was intermediate G 9 E interaction. Genotypes were also significantly different for days to maturity, fresh tuber yield, biomass and harvest index and G 9 E interactions for these traits were also significant. The correlation between inulin content and days to maturity was not significant (r = -0.20), whereas inulin content and fresh tuber yield were significantly associated (r = 0.22). JA 37 and CN 52867 are promising for high yield and inulin content.
