"High transpiration efficiency (TE) is one way to optimize water\r\nuse. Although variation for root morpho-physiological traits\r\ncan strongly affect the water status of a plant, the relationship\r\nbetween root traits and TE is not well understood. A maize introgression\r\nlibrary (IL) derived from the cross between Gaspé Flint\r\n(an early line; donor parent) and B73 (an elite line; recurrent parent)\r\nwere evaluated in order to identify QTLs for root system architecture\r\n(RSA), total biomass (TB), leaf area (LA), transpiration\r\nrate (TR), transpiration efficiency (TE), flowering time (FT), grain\r\nyield (GY) and yield components (YC). Two different experiments\r\nwere carried out in order to study the genetic control of i) RSA, FT,\r\nGY and YC in response to drought in field conditions, at UNIBO,\r\nItaly and ii) TE, TR, TB and LA in controlled environment at different\r\nVPD, at ICRISAT, India. Differences in leaf area among the IL\r\nlines explained only 40% of the transpiration differences under\r\nhigh evaporative demand. QTLs were identified for all investigated\r\ntraits. Overlaps between root and transpiration-related QTLs were\r\ndetected on chromosomes 1 and 8. At these QTLs, the Gaspè Flint\r\nallele was associated with a TE decrease. A particularly interesting\r\nQTL for GY and YC, FT and TR was mapped on chromosome\r\n3 (bin 3.3) where the Gaspè Flint allele was associated with an\r\nincrease of both yield and transpiration rate and earliness."^^ .
