Yield in grass seed crops is decreased by seed shattering, which is generally caused by abscission . Abscission layer development in perennial ryegrass, Lolium perenne L., was investigated to determine its histogenesis in relation to the morphological stages of the inflorescence . Spikelets were fix

Inbred lines possessing different genotypes at three isozyme loci, PGI-2, GOT-3 and ACP-1, were produced by two generations of selfing from two contrasting cultivars of perennial ryegrass. Four separate F2 populations were obtained by selling or crossing F1 plants from crosses between cultivar inbre
In seed crops of perennial ryegrass, Lolium perenne L ., yields are low and only 15 to 20% of the florets produce a harvestable seed . This study was conducted to determine if seed abortion was a major cause of low floret site utilization (FSU) and therefore of low seed yield in spaced plants . Spik
