A method of screening for spike fertility in wheat

SUMMARY Wheat grain yield is often associated with grain number/m 2 . Spike fertility (SF), i.e. the quotient between grain number and spike chaff dry weight, is a major component of grain number/m 2 determination. Several methodologies have been proposed in the literature for field determination of SF, but they are tedious and expensive. Also, no comparison between methodologies has been done. The feasibility of using wheat SF as a selection...
