Abstract
Two cultivars belonging to A. cepa var. viviparum are cultivated in India. One of these is a diploid (2n=16) and is karyotypically heterozygous. The other is a triploid and contains a diploid and a halploid set (AA B) in its karyotype. Both cultivars have only one chromosome with a satellite in their somatic complements. The triploid is extensively cultivated in Kashmir.
