EVALUATION OF SOME DASHEEN TYPE COLOCASIA (Colocasia esculenta var. esculenta) UNDER BIHAR PIATEAU REGION

Abstract

A collection of 30 accessions of less diversified group of Dasheen type Colocasia (Colocasia esculenta
var. esculenta) have beeD; made from fourteen different locations of the country and were evaluated
under field trial for growth, tuber yield with its attributes and qualitative parameters during kharif
seasons of 1994, 1995 and 1996. Wide variations in plant height, leaf length/breadth ratio, sheath
length, tuber yield, dry matter(%), digestible starch content (%), protein content (%), oxalate content
(%) and in organoleptic test were observed. On the basis of tuber yield and qualitative aspects,
three distinct types viz. E.Ac.-l, EAc.-20 and E.Ac.-26 were identified for commercial cultivation
for this region. These could also be utilized as donor germplasm in crop improvement
