    Chapter 2 Plant Breeding
    (Tea Research Foundation (TRFCA), 2006) Kumwenda, A.S.; Kumwenda, A.S.
    The aims of the plant breeding program are to produce new, high yielding and high quality vegetatively propagated (VP) cultivars and composite plants that are adapted to local conditions. This is achieved by crossing selected parental stocks of cultivars and plant selection based on ease of rooting, quality, yield and easily rooting invigorating rootstocks and high quality scions VP cultivars for the production of superior composite plants.

    Fluid Bed dryer monitoring and control. In the dryer, the first parameter that is measured is the input temperature.When the dhool enters, the dryer, there is around 2.5 times as much water as dry matter in it.When this highly mobile portion of the dhool moisture has been lost, (at about 40% moisture content wet basis) the rate of drying will start to fall. Once all the free moisture in the tea has been evaporated, we still have some further moisture to evaporate. This is the amount of water that the dry tea is capable of picking up from the atmosphere in storage, in a hygroscopic manner.
