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.

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

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.

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.

This project followed on from the production of the SOILpak manual (A soil management package for cracking clays).

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

Report on Overseas Travel, June-July 1994 Helen McFadden

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

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.

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.

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.
