초록

탄자니아(United Republic of Tanzania)의 연방인 잔지바르의 옥수수 종자보급 개선을 목적으로 자유방임품종4종 (Tuxpeno-1,Staha, Situka, TMV-1)을 탄자니아 본토로부터 2006년도에 도입하여 키짐바니 농업연구소에서 적응시험을 수행하였다. Tuxpeno-1이 3.9 t ha-1로써 네 품종 중 수량이 가장 높았으며, Staha는 3.8 t ha-1, Situka는 3.0 t ha-1, 그리고 TMV-1은 2.0 t ha-1의 수량을 보였다. 이는 각 품종들의 잠재수량성(potential yield)과 비교하여 77%, 72%,67%, 그리고 47% 정도의 수량이다. 수량 차이가 많이 나는 이유로는 양분의 부족이 가장 큰 원인으로 판단된다. 잔지바르의 환경에서 생육이 부진한 TMV-1과 병해충 저항성이 약했던 Situka품종은 보급 품종에서 제외되었다. 키짐바니 농업연구소에서는 본시험 이후 Tuxpeno-1와 Staha 품종의 종자를 생산하여 농가에 보급하고 있다.

To support maize seed program in Zanzibar, a semi-autonomous state of Tanzania, four improved open-pollinated maize varieties (OPVs) were introduced and tested at Kizimbani Agricultural Research Station (KARS) in 2006. In the different environment from Tanzania mainland, Tuxpeno-1 showed best performance with 3.9 t ha-1, followed by Staha (3.8 t ha-1), Situka (3.0 t ha-1), and TMV-1 (2.0 t ha-1). These results are over the average yield of Zanizbar, but less or more than the potential yield by 76%, 72%, 67%, 47%, respectively. It was understood that the lower yield was primarily due to less fertile soil. General growth of TMV-1 was poor, and Situka was revealed to be weak to pests and diseases in the island, so they were not recommended to farmers. KARS started to conduct seed multiplication and supply as a following up program for farmers.
