In a cross of Weitor 702 (a good cooking pea) and Kapuskasing 3880-4 (a poor cooking pea), grown from the F2 to F5 generations in the field, it was found that cooking quality was weakly related to the Ca/phytin-P ratio and to the phytin-P content of the pea. The desirable cooking quality of the Weitor parent was retained to the F0 generation when selection was made from single F2 plants. The data suggest, however, that selection for good cooking quality may be more efficient if started in the F4 generation. The inheritance of good cooking quality appeared to be controlled by two recessive genes, although there was some indication of a gene–environmental interaction.

In a greenhouse study with two varieties of field peas, the cooking quality of the Weitor 702 (a good-cooking pea) was markedly influenced by P and K additions and by the initial fertility level of the soil. The cooking quality of the other variety, Kapuskasing, remained poor regardless of treatment or fertility level of the soil. Ash and total, inorganic, and phytin P content of the pea samples tended to increase with addition of P fertilizer. Correlation coefficients expressing the relationship between cooking quality and chemical constituents of the pea seeds indicated that cooking quality varied with ash and phytin P content.In field studies, soil properties (pH and available P) were not related to cooking quality or chemical properties of peas grown at different locations. Although cooking quality, phosphorus content, and cation content of the pea samples varied according to variety and location, there was no significant relationship between cooking quality and the chemical constituents.The cooking quality of F2and F3seed from a Weitor 702 × Kapuskasing cross varied, but was not related to the chemical properties of the peas.

In a 42,750-ha survey area in subtropical Queensland, rabbit warrens are confined mainly to sandy soils. Within these favoured areas the population is distributed unevenly, and there is further selection for preferred habitats. Detailed studies on a 246-ha area of sandhill showed that the open woodland and grassy open woodland associations contain most warrens per unit area, and also the largest warrens. The quality of habitat for rabbits appears to be determined by availability of food, type of soil, and vegetation cover providing protection from predators. In some vegetation associations, use of burrows varies only slightly, in others there are significant changes. There is a significant correlation between the estimated numbers of rabbits in the population, the total number of rabbits seen on spotlight transect counts in the evening, the numbers of rabbits seen on warrens during late afternoon watches, and the total number of active burrow entrances present in the study area. A list of plant species present and a description of the 23 vegetation associations in the study area is presented.
