Achievements on Somoclonal Variations - Over a dozen varieties have been developed through the exploitation of somaclonal variation. 'Ono' variety of sugarcane is a Fiji disease resistant somaclone of the susceptible cultivar 'Pindar'; it was identified by screening plants regenerated from unselected calli. 'Ono' also shows an yield advantage over 'Pindar'. A sweet potato cultivar 'Scarlet' was selected from shoot-tip culture derived clones.

'Scarlet' is comparable to the parent cultivar in yield and disease resistance, but shows darker and more stable skin colour, which is a desirable quality trait. A geranium variety called 'Velvet Rose' is a somaclone of 'Rober's Lemon Rose'; the new variety has twice the chromosome number of the parent variety. An alfalfa variety called 'Sigma' is a polycross of selected somaclones.

n India, so far somaclonal variation is the only biotechnological approach to give a commercial variety. A somaclonal variant of Citronella java, a medicinal plant, has been released as 'Bio-l3' for commercial cultivation by CIMAP (Central Institute for Medicinal and Aromatic Plants), Lucknow. Bio- 13 yields 37% more oil and 39% more citronellol than the control varieties.

A somaclonal variant of the B. juncea variety 'Varuna' has been released for commercial cultivation as 'Pusa Jai Kisan'. The new variety has bolder seeds and some yield advantage over the parent variety Varuna. A somaclone of khesari (Lathyrus sativus) has low neutrotoxin (BoAA) content; it has been released as 'Ratan' for commercial cultivation.
