Catalogue: 
Three zones of contrasting soil types were identified for paddock 146A using EM38, grain yield and elevation data... Nitrogen was applied post emergence in large blocks (approx 40m x 100m) at three rates (20, 50 and 100kg/ha) with two replicates of each rate in each zone to wheat in 2004 and barley in 2005 and 2006... Grain yield (t/ha) P rate (kg/ha) Flat (heavy soil) Hill (light soil) 0 1.23 1.33 3 1.28 1.40 11 1.07 1.49 fertiliser rates in two zones, Yield increase (t/ha) needed the cost of the extra fertiliser 0.04 0.16..

Hybridity of putative hybrid plantlets was confirmed at the DNA level using published Simple Sequence Repeat (SSR) markers... (a) Shoots were regenerated from very immature ovule cultures of the wide cross between chickpea (ICCV 10) X C. bijugum (ILWC 260), which were rescued in vitro to avoid abortion from the mother plant... (b) The hybridity of such hybrids was confirmed on the basis of DNA polymorphism...

" ATTACHMENT TO PROJECT NO DAQ00107 CROPPING OPTIONS TO LIMIT ROOT-LESION NEMATODES Abstracts from the 5 thInternational Congress of Nematology 2008 Crop rotation for the management of root-lesion nematodes in the northern grains regions of Australia... Root-lesion nematodes, Pratylenchus thornei and P. neglectus are widely distributed in the northern grain region of Australia which encompasses inland northern NSW and south-east Queensland... The presence of root-lesion nematodes (Pratylenchus thornei and P. neglectus) and stunt nematode (Merlinius brevidens) in some parts of the northern...

Even though spraytopping with Gramoxone #is generally safe on sub-clover, this treatment resulted in a significant reduction in seed set for Prima Agland clover, Frontier Abalansa clover, Orion sphere medic and Eastern star clover... AIMS To evaluate the impact of two common spraytopping treatments, glyphosate and Gramoxone , on seed production of new pasture cultivars and elite lines nearing commercial release... Fifteen unsprayed (control) plots were also evaluated for each cultivar/line...

Catalogue: 
Chickpea itself has no close wild relatives within its species Cicer arietinum, and earlier attempts to cross chickpea with distant relatives using conventional hybridisation methods were unsuccessful... The results of experimental research are used to improve the process as tissue culture media and methods continue to be optimised in ongoing research... 9) One week later, or when plantlets have grown about the way up the vessel, remove the culture vessel completely 10) Cover the plantlet with a clear cellophane bag with aeration holes (we use supermarket bread bags)...

" Attachment 3 Project DAW00141 Developing a sensitive dry seed test to detect seed-borne viruses in bulk seed samples of wheat A diagnostic test for Wheat streak mosaic virus in bulk samples of wheat seed.. A test to detect presence of seed coat contamination with Wheat streak mosaic virus (WSMV) in bulk samples of wheat seed was developed and made available commercially through AGWEST Plant Laboratories... The aim of the research was to develop a robust, routine diagnostic test to detect contamination with WSMV in representative bulk samples from wheat seed stocks...
