Responses of Oryza glaberrima accessions to rice stresses and their morphological characteristics.

Oryza glaberrima accessions were characterized for their tolerance to drought, African rice gall midge, blast and some agronomic traits to source for donor resistant genes. The experiment was conducted at both Badeggi and Edozhigi. The blast and drought experiments were drilled in a sin gle row of 70cm each spaced 20cm apart at Badeggi. While the African rice gall midge and morphological characterization exper iments were conducted in a randomized complete block design replicated three times. Entries were planted in a single row o f 5m each in the replicate and spaced 20 x 20cm. Re sults showed that 25% of the entries showed resistant reaction at 32 days of water stress. At 5 weeks none of the varieties sho wed resistant reaction to blast. For African rice gall midge the result of the two l ocations showed that there were resistant genes ava ilable in this population. 14% showed immune reaction (score 0) to the insect at Badeggi. At Edozhigi location none of the entrie s was immune or resistant, however 4 % were moderately resistant (s core 3). The morphological description showed high variability among the entries. Therefore useful donor genes for drought a nd African rice gall midge could be made available in this population.
