Abstract

Field screening of linseed genotypes for resistance to wilt in the north central plateau zone of Odisha

Highlights

  • Linseed or oil flax (Linum usitatissimum L.) is the second most important winter oilseed crop and stands next to rapeseed- mustard in area and production in India

  • In India, during 2013-14 linseed is grown in an area of 292.1 thousand hectares with annual production of 141.2 thousand tonnes and productivity of 484 kg/ha

  • All the genotypes were assessed visually based on percentage of infected plants for each entry in wilt-sick plot and categorized into six types (Singh et al, 2010) as detailed below: No wilt disease = Immune Up to 5% wilt = Resistant 6 to 10% will = Moderately Resistant 11 to 20% wilt = Moderately Susceptible 21 to 50% wilt = Susceptible Above 50% wilt = Highly Susceptible

Summary

Introduction

Linseed or oil flax (Linum usitatissimum L.) is the second most important winter oilseed crop and stands next to rapeseed- mustard in area and production in India. It has an important position in Indian economy due to its wide industrial utility. In India, during 2013-14 linseed is grown in an area of 292.1 thousand hectares with annual production of 141.2 thousand tonnes and productivity of 484 kg/ha. We need a high yielding linseed variety for late sown conditions with resistance to wilt. With this objective, field screening of linseed genotypes for resistance to wilt was initiated
