Sweet potato (Ipomoea batatas L.) and taro [Colocasia esculenta (L.) Schott] are
the important tuber crops used as staple or subsistence food by millions of people
in developing nations. Both tubers and leaves of these crops are an alternative
source of dietary energy. Visibility of these crops as life support crops species
has been enhanced during post super cyclone in Odisha and Tsunami in coastal
states of India. Genetic diversity of these crops, and their wide distribution and
potential to adapt in harsh environmental condition advocate for their further
exploitation to develop stress tolerant crops with valued traits. Gene fl ow through
conventional breeding is hindered owing to fl owering behaviours, cytogenetical
anomalies in taro and hexaploidy coupled with self incompatibility in sweet potato.
To make these crops more resilient, an extensive study was taken up integrating
conventional and non conventional methods to tap the vast potential of genetic
diversity in isolating the stress tolerant sweet potato and taro genotypes. The
varietal gene bank of sweet potato maintained at the Regional Centre farm of the
Central Tuber Crops Research Institute (CTCRI) were also tested under in situ
to study tolerance to environmental stresses. Under such conditions, percentage
of leaf damage and vine weight were recorded to identify the varieties to cope
with unfavorable agro-climatic conditions. Results to isolate and develop stress
tolerant sweet potato and taro and, their impact on livelihood security under
climatic adversities are discussed.
