Registration of ‘Pawe-2’ Rice Variety for Upland Ecosystem in Ethiopia
below the potential of the crop due to, among others, limited availability of stable, high yielding and disease tolerant upland rice varieties. This problem has seriously limited production of the crop in the country.
Objective: The research was conducted to evaluate and release a stable high yielding and disease resistant/tolerant upland rice varieties for the typical upland rice ecosystems in Ethiopia.
Material and Methods: The rice variety (currently named Pawe-2) introduced from Brazil in 2012 was evaluated along with NERICA-4 and Fogera-1 as local and standard check varieties, respectively, at Pawe and Metema (typical upland rice ecosystems) beginning from a 2013. After the evaluation of the variety for six years, verification trials were conducted in 2019 and in 2020.
Results: Pawe-2 had better performances for most agronomic traits than the check varieties. The newly released variety, ‘Pawe-2’ had an average grain yield of 5058.93 kg ha–1, and it had yield advantages of 15.68% and 13.52% over Fogera-1 and NERICA-4 rice varieties, respectively, as shown by the results of the verification trails conducted in 2019. Moreover, Pawe-2 had a higher biomass yield, larger grain size, white caryopsis color, early maturity and resistance to diseases and pests than the check varieties.
Conclusions: It is concluded that the variety ‘Pawe-2’ is superior to the other varieties in terms of yield, yield stability, and resistance to pests and diseases. Therefore, the National Variety Release Committee approved Pawe-2 for cultivation in the mid altitude (750–1800 meters above sea level) and similar typical upland rice ecosystems in Ethiopia.
