    Maximising genetic gain from family and within family selection : final report 011/343
    (Sugar Research Australia Limited, 2016) Parfitt, R; Wei, X; Stringer, J
    The aim of this project is to improve the effectiveness and efficiency of selection in progeny assessment trials (PATs). These improvements will result in increased rates of genetic gain and the release of more productive varieties for the Australian sugarcane industry.

    Optimisation of the initial stages of the New South Wales selection program : SRDC final project report BS96S
    (2002) Piperidis, G
    The main aim of this project was to obtain the basic information required to implement an efficient and effective breeding and selection program in NSW. However, the project suffered major difficulties that affected the delivery of the proposed objectives. In spite of this, useful information that will have impact on the NSW selection program was obtained from the available data. In areas where two-year crops predominate, selection from Stage 1 and Stage 2 trials should be applied based on the data from two-year old crops. In addition, there was a strong correlation between the estimated net merit grade (NMGVol) and calculated net merit grade (NMG) in both the one-year and two-year Stage 2 crops at Broadwater. The correlation between the one-year NMGVol and the two-year NMG, however, was not significant. The results also show that family selection combined with visual selection in Stage 2 was generally more effective to identify elite clones in Stage 3 than family selection alone. Additionally, when the Brix of clones was taken into account the efficiency of identifying elite clones was increased even further.

    Optimum selection strategies in original seedlings particularly for heavily lodged crops : SRDC final report BS46S
    (1999) Kimbeng, CA; McRae, TA
    The objectives for this project were: to evaluate the effectiveness of family selection in the plant crop of original seedlings of sugarcane grown to full crop potential in the Burdekin region. The crop will probably be heavily lodged; to evaluate the effectiveness of visual (mass) selection in the young first ratoon crop; to determine the level of family performance in seedling populations required for a family to be selected. Information derived from this study would enable the breeder to design the most cost effective and efficient selection scheme for this stage of the breeding program for the Burdekin region
