A case for closely studying spikelet number and its possible determinants for increasing grain yield in wheat

A case for closely studying spikelet number and its possible determinants for increasing grain yield in wheat

Journal of the Australian Institute of Agricultural Science 46(4): 229-232

Current views and research on yield determination are considered. It is concluded that sink rather than source size is the more advantageous. Interdependence of the sink components, numbers of ears/plant, spikelets/ear, grains/spikelet and grain size, apparently results in compensating effects when one component is altered. It is suggested that, as development proceeds and component number or size is determined, opportunity for compensation becomes limited.
