Development of dual disease resistant Basmati rice varieties offer significant economic advantage and impetus to sustainable crop production.

ABSTRACT:

Introduction

Bacterial blight and blast are the major diseases causing production losses to an extent of 31.52% to 67.79% in Pusa Basmati 1121(PB1121) and Pusa Basmati 6(PB6), respectively. Use of chemical pesticides leads to increased cost of cultivation, degradation of environment and human health while affecting international trade.

Objective

The study aimed at developing bacterial blight and blast resistant Basmati rice varieties and to assess their impact in farmers' field.

Methods

A marker assisted selection from intercross of backcross derived lines was implemented to incorporate bacterial blight resistance genes xa13 and Xa21; along with blast resistance genes Pi2 and Pi54. The developed lines were evaluated across multiple environments before release as comme
