Tel: +45 89993500; fax: +45 89993501; E-mail: Birte.Boelt@agrsci.dk The yield components in grass seed crops are identified as: The number of reproductive tillers, the number of florets per tiller and their success in producing a seed (floret site utilisation, FSU) and seed weight.
The majority of species in grass seed production in Denmark require a dual flower induction to initiate reproductive growth, and the traditional Danish production system is to establish grass seed crops undersown in at cover crop (companion crop). The management of these double crops production systems has attained much focus in research i.e. determination of optimal cover crop species, seed rate, row distance, nitrogen fertilisation rates and distribution between autumn and spring etc. Data from these experiments have shown that in slow establishing species as smooth stalked meadow grass (Poa pratensis, L.) and red fescue (Festuca rubra, L.) a low number of reproductive tillers may restrict the seed grower in obtaining the optimum seed yield. However, due to the large number of experiments, knowledge is available to avoid a low number of reproductive tillers to restrict seed yield.
In a number of grass seed crops cultivation practice includes the application of a growth regulator to avoid lodging before flowering. It is assumed that grass seed crops without any lodging at flowering have a higher FSU and hence a higher seed yield potential. Thousand seed weight (TSW) is normally determined in the pure seed lot, and often only very small variation is found within the same variety. This may be due to the fact that some seeds are lost due to shedding before harvest, some are lost in the harvest operation and some are lost during cleaning. In general it is assumed that the seeds lost during harvest and cleaning operations are small ‘empty’ seeds, however, experiments are initiated to examine to what extent seed weight may be increased by cultivation techniques.
Towards Resolving Vegetative and Reproductive Growth Conflicts in Turfgrasses Thorogood, D. and Armstead, I.P.
Department of Plant Genetics and Breeding, Institute of Grassland and Environmental Research, Plas Gogerddan, Aberystwyth, Ceredigion, SY23 3EB, United Kingdom.
Turf quality is entirely dependent on vegetative characteristics, yet to produce a commercially viable turfgrass variety, its seed production potential must be optimised. However selection for seed production traits that are dependent on preferable allocation of resources from vegetative to reproductive organs will inevitably be negatively correlated with turf performance. The proportion of florets that produce a seed, and seed retention are two reproductive traits that are independent of vegetative growth performance traits and are therefore worth targeting. This paper focuses on seed set in perennial ryegrass for which there is considerable variation. Our approach has been to simply identify major QTL in mapping families that influence seed setting ability. In particular, we wanted to know whether the QTL identified were determined by resource allocation factors, that might suggest some compensatory mechanisms which would lead to no increase in overall seed yield potential, or, more significantly, genetic breakdown of gamete/embryo development processes. By comparing orthologous regions in rice, we also wished to identify putative orthologues of genes underlying these QTL, the physiological basis of which may already be known.
Relation Between Seed Yield Potential and Turf Quality in Poa pratensis L.
Prończuk S., urek G.
Plant Breeding and Acclimatization Institute, Radzików, 05-870 Błonie, POLAND The relation between seed yield and turf quality was disputable from many years. Also search for good ‘marker’ traits for seed yield and turf quality predicting is still in progress.
