Genetic control of cone clusters and precocious flowering in Pinus sylvestris

A Scots pine clone bearing cone clusters transmitted precocity to a portion of its progeny resulting from crosses to clones having normal cone distribution. Inheritance appeared to be governed by a single major gene whose expression was dominant or recessive depending upon which clone it was mated to. Differences of reciprocal crosses indicated maternal or cytoplasmic influence. This genetic variation in precocity can be used to reduce the generation interval, thereby facilitating genetic studies and breeding programs. Seed yield per pollination bag was several times greater for cone clusters than for normally distributed cones although viable seed per cone was 20% less. This can reduce the cost of producing hybrid seed if artificial pollination is required.

Ryegrass hybridisation: The effect of artificial isolation materials on seed yield and floral environment

A comparison of conventional glassine pollination bags and recently-developed terylene isolation bags for artificial hybridisation of perennial ryegrass (Lolium perenne) is reported.
