GENOTYPE X ENVIRONMENT INTERACTION IN SWEET POTATO

Abstract

Sweet potato (Ipomoea batatas (1.) Lam.) is an important food crop grown in many parts of the tropics and sub-tropics. It is grown over a wide range of environments and environmental conditions are known to have significant influence on tuber yield[3-4]. Recently the Central Tuber Crops Research Institute, Trivandrum has identified a few high yielding hybrids and germplasm selections of sweet potato for advanced trials. The objective of present study is to find out the stability of sweet potato genotypes for tuber yield in different environments within Kerala State.
