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

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.

A number of laboratory experiments have been run since 1989 to address the area of distribution variation.

I have prepared these notes for our meeting of July 2S.

This project commenced on the 1st July, 1993. Since that time the following has occurred

The work has identified condensed tannin (CT) as occurring in cottonseed hulls but not in cottonseed kernels. Approximately 20% of the CT in cottonseed hulls is extractable and 80% is bound to protein and fibre.

The anisotropic nature of the soil continuum does not lend itself to classification schemes constructed as many are by predetermined hierachical classes.

A new glasshouse was constructed at Narrabri to enable an expansion of the backcrossing of genetically engineered characters into CSIRO cotton varieties.

Nitrification inhibitors were successfully used to improve the recovery of fertilizer N in the irrigated cotton-growing system.

In order to obtain information of its environmental fate under conditions of use in the Australian cotton industry, this major study was initiated in 1990-91.

The aim of the project, to enable cotton to be grown in experiments in the disciplines of breeding, agronomy and entomology by the CSIRO Cotton Research Unit at the Australian Cotton Research Institute, has been met O

The funds requested in the application were for Dr Christian to spend 6 weeks in the laboratory of Dr Art Mcintosh and Dr Carlo lgnoffo in Columbia Missouri, working on aspects of the project "Genetic Engineering

To make the OZCOT cotton crop simulation model more robust and versatile; enabling it to be used for decision support in a broader range of applications and situations. This involved five specific objectives: 1.
