Titre : RFLP and quantitative trait loci analysis of seedling thermo-tolerance in contrasting genotypes of pearl millet

Pays : Inde

Projet de recherche pour le Développement : R5487

DFID Programme : Plant Sciences Research

Organismes de mise en œuvre

Durée : Start Date : 01-04-1993 End Date : 30-09-1995

Objectif
The objectives of the project are : To produce millet crosses utilising existing characterised genotypes.  ; To produce F4 selfed bulks from selected crosses.  ; To assess seedling thermo-tolerance of F4 selfed bulks.  ; To use F4 selfed bulks to map thermo-tolerance traits using RFLP/QTL analysis.

Descriptif
In India, pearl millet is the principal grain and fodder crop in arid and semi-arid areas bordering on the Thar desert in the states of Rajasthan, Haryana and Gujarat, with Rajasthan accounting for 45% of the total area under pearl millet in India. Although pearl millet shows considerable environment adaptation to these marginal areas, its yield there is not only low but also highly variable. Seed and biomass yields are severely constrained by extremes of temperature and by unreliable and irregular rainfall. Poor seedling establishment, and consequent crop failure, result from the extreme high temperature prevalent at the start of the growing season. Improvement of the adaptation of seedlings to high temperatures has been given by ICRISAT an estimated annual value of success of over $44 million.
