Appropriate Crop Improvement Research Programmes Continue to be Implemented

One of the major constraints to productivity and the development and growth of Tanzania’s coffee industry has been caused by the continued cultivation of old varieties that are low yielding and highly susceptible to the major coffee diseases, coffee berry disease (CBD) and coffee leaf rust (CLR) for Arabica and coffee wilt disease (CWD) for Robusta.

Objective of Crop Improvement Research Programmes

One of TaCRI’s major objectives is to identify high yielding varieties resistant to CLR, CBD and CWD with large bean size and high cup quality that perform optimally within the diverse coffee production areas of Tanzania. The role of the Crop Improvement research programme is to develop and promote new varieties of Arabica and Robusta coffee that deliver high yields, are disease resistant, and which have good bean size and cup quality.

Achievement of Crop Improvement Research Programmes

To date TaCRI has released 19 Arabica coffee hybrid and four Robusta varieties that combine high yields and good beverage quality with resistance to the devastating diseases – coffee leaf rust (CLR) and coffee berry disease (CBD) for Arabica and coffee wilt disease (CWD) for Robusta. These varieties are being mass multiplied (through vegetative multiplication and tissue culture multiplication) for distribution to coffee growers around the country.
