Collection and Evaluation of Genetic Resources of Tuber Crops in Orissa

Abstract

One of the fastest and the easiest ways of developing improved varieties is to
properly exploit the available genetic variability. However, the cultivated, semicultivated
and even the wild forms in tuber crops have been lost considerably due
to erosion and efforts are thus needed to collect and preserve the exsiting variability.
Most tuber crops are highly heterozygous in nature and exhibit considerable
variation.
