Screening rice germplasm from north east hill region for tolerance to aluminium toxicity

Aluminium toxicity is one of the most important factor among the edaphic stresses in the chemical environment in upland, lateritic soils. This study, helped in identification of 27 traditional varieties (15 from laboratory study and other 12 in phytotron study) tolerant to Al toxicity. The magnitude of affect due to Al was also recorded in different traits. These tolerant germplasm would be useful as such or in the breeding programme as donor parents.
