    Mintaro is a cream seeded Sub-Clover that belongs to the family of Trifolium subterranean ssp. brachycalycinumn and was derived from hybrid selections between Rosedale and other elite germplasm sources. Mintaro demonstrates a prostrate to semi erect growth habit and persists well on various alkaline soil types. It has early to mid season maturity and suited to medium to high rainfall environments with a growing season of 6 months. Mintaro has been developed as a superior alternative to Rosedale and Clare with improved hard seed levels providing protection against false breaks, better regeneration and excellent winter and early spring production. These attributes combine to make Mintaro suited to either permanent pasture or medium term cropping rotations. Mintaro will provide the benefits of soil nitrogen along with an effective disease break.

     

     

    Maturity:

    Approximately 114 days (Perth)

     

    Pest Resistance:

    Mintaro has been rated with low tolerance to Redlegged Earth Mite (Halotydeus destructor) but has shown low to moderate resistance to Blue Green Aphid (Acyrhosiphon kondoi). Control of these insects is still recommended at the seedling and developmental stage to maximise growth and production.

     

    PBR:

    Mintaro has been granted protection under PBR. Unauthorised commercial propagation or any sale, conditioning, export, import or stocking of propagating material of this variety is an infringement under the Plant Breeder’s Rights Act 1994. Heritage Seeds Pty Ltd has an exclusive licence for the production and marketing of Mintaro.

     

    Key Benefits:

    • Very vigorous establishment and winter Forage production which will provide much greater productivity than similar maturity Sub Clovers
    • The high hard seed level and very good pest disease resistances ensure Mintaro will be a productive, perennial component of your pasture. 

     

    Disease Resistance/Tolerance:

    Mintaro is resistant to race 1 of Clover scorch (Kabatiella caulivora) (race commonly found throughout southern Australia) and highly resistant to race 2 (highly virulent race found in WA).

     

    Variety Management/Agronomy:

    Mintaro has demonstrated the ability to provide higher seed yield and hard seed levels compared to Clare and Antas in lower rainfall environments. This characteristic allows Mintaro to build up a greater reserve of seed in the soil over time, thus enhancing persistence and productivity over many years.

     

    Mintaro has demonstrated excellent winter and early spring productivity and will out produce other varieties such as Clare due to its earlier maturity. It produces very large leaves that makes it attractive to stock and provides improved levels of digestibility. Mintaro is a low oestrongenic cultivar and will not cause fertility problems for grazing livestock.

     

    Care must be taken with new sown pastures so as not to overgraze too early as plants can be pulled from the ground. Light grazing during the establishment period will help control weeds and encourage dense prostrate growth.

    Sub Clovers

    Sub clovers are amongst the most widely used pasture legumes in southern Australia. They are typically used in low-medium, winter rainfall dominant areas for extensive grazing operations. The term sub clover refers to a group of three species:

    Subterraneum, Yanninicum & Brachycalycinum.
