The Institute for Crop and Food Research was formed in 1992 as a New Zealand-based biological science Crown Research Institute researching new knowledge in five main areas: sustainable water and land use high performance plants personalised foods high value marine products biomolecules and biomaterialsIt had an annual turnover of approximately $53 million and a staff of 370. Its research funding came from a mix of local and international industry and government sources, and its research spanned both fundamental and applied research.On 6 June 2003, a Piper Navajo Chieftain on a charter flight from Palmerston North to Christchurch crashed on approach to Christchurch Airport, killing the pilot and seven Crop and Food employees, and seriously injuring two others.On 1 December 2008 Crop & Food Research merged with HortResearch to form New Zealand Institute for Plant and Food Research trading as Plant and Food Research.

Wheat streak mosaic virus is an established major threat to wheat in North America and is newly identified in Australia. Three genetic sources of resistance were examined, Wsm1 (from an alien translocation), Wsm2 (from CO960293-2), and c2652 (selected in Canada). We report their effectiveness in the field when inoculated with an Australian WSMV isolate. Also included were advanced breeding lines with and without Wsm2 and a number of elite Australian cultivars. ELISA testing on individual plants indicated we achieved between 85% and 100% infection with WSMV in susceptible lines following artificial inoculation which reduced their yield by 22 to 44% and height by 19 to 51%. Kernel weight was significantly affected in some of the susceptible lines. All three sources of resistance (Wsm1, Wsm2, c2652) and Wsm2 derivatives protected wheat against infection despite repeated inoculation. Inoculated resistant plots were virtually disease free and suffered neither significant yield loss nor height reduction. National yield trials of the breeding derivatives showed no difference in yields between those with and without Wsm2 under non- WSMV conditions. © 2012 Australasian Plant Pathology Society Inc.

To reduce crop N requirements without reducing productivity it will be important to identify and quantify the inessential N in crop canopies. Field experiments established in October 2005 and October 2006 at ADAS Terrington, UK, and in June 2006 at Lincoln, New Zealand, tested wide-ranging N levels applied to one variety of feed winter wheat. Amounts of structural, photosynthetic and reserve N (SN, PN and RN, respectively) were defined and measured in components of the crop canopy (leaf lamina, leaf sheath, true stem and ear/chaff and grain) at anthesis and harvest, and the amounts of N remobilised from the PN and RN pools were calculated. At anthesis, RN accumulated for all N treatments in all experiments, and accounted for 44% of above-ground N (AGN) in optimally fertilised crops. This RN was principally located in the true stem, but was observed in all crop components at non-limiting fertiliser N treatments. Post-anthesis, RN appeared to be remobilised in preference to PN, thereby contributing to the maintenance of green area during the grain-filling phase and photo-assimilate production. The efficiency of post-anthesis N remobilisation of true stem RN was low (48%) compared to chaff (56%), leaf sheath (61%) and leaf laminae (76%), and in well fertilised crops significant quantities of '. accumulation' RN remained in true stem at harvest. The accumulation of significant quantities of RN at anthesis, even with deficient N supplies, suggests that it has a functional role during the grain-filling phase of growth. As '. accumulation RN' does not contribute to either the quantity or quality of grain, it reduces N-utilisation efficiency (UTE). Potential to improve UTE exists through increasing RN use during grain-filling and reducing '. accumulation RN' in non-photosynthetic organs. © 2011 Elsevier B.V..

The sensory qualities related to consumer freshness perceptions are dependant on the food considered. However, it is not clear how ingredients in combination with baked product shelf-life influence consumer judgements of freshness. A range of model cake samples (n 1/4 24) were produced using a 4 × 3 × 2 factorial design, which included four different sweeteners, three different fat types and two different times from baking. Descriptive sensory analysis was carried out on all cake samples, using a panel of ten trained assessors and a defined vocabulary of 31 terms. The sensory properties of cakes were significantly (p < 0.05) influenced by sweetener type, fat type and time from baking. Principal Component Analysis (PCA) revealed twelve cake samples with the largest sensory variation that were further selected for consumer testing. Representative consumers (n 1/4 120) rated the perceived freshness of the selected samples. Consumer perceptions of freshness were significantly (p < 0.05) influenced by sweetener type, fat type and storage. Three consumer segments that were homogenous in their freshness perceptions were identified. Partial Least Squares Regression (PLSR) was applied to determine relationships between sensory descriptions of samples and consumers' freshness perception of samples in each segment. Using PLSR models, consumer freshness perceptions for the twelve remaining cakes not evaluated by consumers, but assessed by descriptive sensory analysis, were predicted for each consumer segment. © 2009 Elsevier Ltd.
