    Collaborative competition

    I was reading Peter Amer’s “Pre-competitive collaboration” in which he discusses the interaction between private and public sectors in research and innovation, as someone coming from the private sector. Nice commentary. I work for a public university, so I come from a slightly different position. In my quantitative genetics work, most of the methodologies are…

  • Leaking genetic gain: not quite a selection index

    Leaking genetic gain: not quite a selection index

    A few years ago I was talking with a breeder who spent substantial time running genetic analyses, with fairly sophisticated linear mixed models. From there the breeder obtained BLUPs for a couple of selection criteria (using an animal model with heterogeneous site variances), heritabilities, genetic correlations, etc. The typical stuff. Then came the leak: let’s…

    Long-term and longer-term

    Last Tuesday I had a very interesting visit (coordinated by Dr Verónica Emhart) and discussion with the breeding team at CMPC in Los Ángeles, southern Chile. This is part of a trip visiting organisations in Chile during December and January*. I had offered to give a talk about our work breeding for solid wood products…

  • Names and things

    Names and things

    There was a time when we used to take one or more field crews and we would measure trees. As in getting dbh with a tape, height with a clinometer, form on a scale from 1-6 or 1-9 or whatever. Sometimes we would extract increment cores or use a time-of-flight tool to get velocity, etc.…

    At the core of your breeding programme

    Surely you have been in this situation: meeting, there is coffee and biscuits at the back, some fruit if you’re lucky, and people with ideas flying about how to improve or change the breeding programme. Some of the ideas look easy to implement, others need a huge amount of work, and everyone has a different…
