What can we use it for?

1. Ecogeographic survey for locating diversity

2. Planning field exploration and germplasm collecting

3. Design, management and monitoring of in situ reserves

4. Site identification for germplasm introduction

5. Site identification for germplasm evaluation

GIS Application for PGR management

Major pearl millet growing areas in India

GIS Application for PGR management

Gaps in collection

Unique collections

• Looks for gaps

• Reasons for no collections• No efforts

• PM not grown

• Climate not suitable

• Climate suitable-other crops important

Mapping of pearl millet collecting sites against cultivation area in India - 1993

GIS Application for PGR management

Mapping of collecting sites against soil types

Need some more collections from red and yellow soil types

GIS Application for PGR management

Mapping of Pearl millet collections from different climatic zones of India

Pearl millet collections from major climatic zones of India

Most collections are from arid and semi-arid tropics

Few collections from sub-humid - dry as well as wet climate

GIS Application for PGR management

Mapping of pearl millet collecting sites against total annual rainfall zones of India

Majority of collections are up to 1000 mm rainfall

Some are up to 1400 mm rainfall

GIS Application for PGR management

Mapping of pearl millet collecting sites against total rainfall in growing season (July – November) in India

Maps for individual months can be generated

GIS Application for PGR management

Most collections are between temperature range of 18-20

Followed by 20-22

Few from 22-24 and 16-18

Mapping against average minimum temperature grid

GIS Application for PGR management

Maximum temperature grid

Most collections are from 30-35 0C

Gaps in collection from low max. temp

GIS Application for PGR management

Most of the collections between 0 to 400 elevation

Some from between 400 to 800

Few from from 800 to 1000

Rare from greater than 2000
