Abstract
The inheritance of net photosynthesis and transpiration efficiency in spring wheat under drought were studied in two years in order to determine their heritability. The parents, F(1) and segregating generations (F(2), BC(1), BC(2)) of four crosses between each of two drought-resistant and two drought-susceptible genotypes were evaluated under drought in pots under glasshouse conditions. Measurements of gas exchange were made using a portable gas-analysis system. Generation means and variance component analyses of the data suggested that these traits are simply inherited and controlled mainly by additive genetic variation. Narrow-sense heritability estimates varies between crosses from 61% to 84% for net photosynthesis and from 88% for transpiration efficiency.
