To help coordinate and ensure good collaborative ties between these research groups and to broaden the understanding of soil salinity within the industry, the CRC initiated the development of a Strategic Plan on salin

The aim of this project is to.assess the efficacy of three new classes of hydrolase genes that might have insecticidal activity when introduced into transgenic cotton.

To develop cotton varieties capable of germinating and establishing in cool soils, seed of Siokra S324 was mutated to induce variation. Ii.

This project focused on the control of nutgrass. Nutgrass (Cyperus rotundus) is considered to be the world's worst weed and inf es ts over 15% of the cotton growing area.

The recent pioneering attempts of several cotton growers to produce organic cotton presents an opportunity to monitor pest populations in the absence of synthetic insecticides.

Objectives To continue the development and validation of a series of micro-computer based decision support packages (initially hydroLOGIC and entomoLOGIC) under the generic name CottonLOGIC.,

This project supports the maintenance of fibre testing facilities at the Australian Cotton Research Institute.

The objectives of Dr Byrne's visit to Australia were: 1.

A thesis submitted for the degree of Doctor of Philosophy in the School of Agricultural Science

In September 1993 the Management Committee of the National Program for Irrigation R&D requested the authors to prepare a briefing paper on Technology Transfer.

Annual Report 1993-1994

Mr. Martin Dillon was not able to attend the congress, as it coincided with the birth of his son on 24 November 1993. However, Martin Dillon and Dr.

This project examined genetic variation in Helicoverpa populations using variation in mitochondrial DNA (mtDNA) and variation in quantitative traits, and was supported by ARC as well as CRDC.

The spatial variation in crop yield, and the field-based factors that contribute to it, is developing as a subject of importance to both the farming and wider communities.

Aim: To investigate the sensitivity or tolerance of Australian cotton varieties to levels of UV-B expected to exist in the foreseeable future

In this and a related project funded by ARC, four fungal isolates of each of two common species were compared for their effect on plant growth.

The Second Canberra Bacillus thuringiensis Meeting was held in the Manning Clark lecture theatre complex at the Australian National University from 21st to 23rd September 1993.

During this trip I was able to liaise successfully with the following colleagues concerned with resistance and its management: Drs Rick Roush (Cornell), Alan Devonshire (Rothamsted), Chris Curtis (London School of Hyg

Aims: 1. To determine the rates, form and placement of fertiliser appropriate to alleviate potassium deficiency and premature senescence. 2.

This project was initiated in 1991, following concern expressed by local cotton growers about suspected high insecticide resistance at St George.
