RECENT STATUS OF GENETIC DIVERSITY OF WHEAT IN PAKISTAN
Amir Afzal
Abstract
ABSTRACT Genetic diversity occupies vital status in the stability of a species as it make available the basic adaptation to the principal biotic and abiotic ecological circumstances, and allows revolution in the genetic masterpiece to handle modifications in the environment. Magnitude of genetic variation exist in the crop. High yielding wheat varieties with narrow genetic base and influenced by grower/consumer preference has led to cultivating fewer cultivars over the large region generating genetic liability to stress not only in country but in further parts of the biosphere. Keeping the facts in view pedigree of wheat advanced material evolved in different research institutes and universities was studied intensely using the technique of Coefficient of Parentage to explore the extent of genetic diversity in material. Finding of the study were not very optimistic. Investigation indicated that the accessions could be allocated into two groups at 12 dissimilarity index, wherein one group contained only eighteen genotypes while the lingering fifty five accessions relates to alternative group (B).It was exposed that material advanced under the organization of same research executive was not inherently diverse. Out of one hundred and twenty eight PASTOR was the most recurrent (13.28%) while, KAUZ (8.59%), INQ-91(7.81%) SOKOLL (7.03%), Ae.AQUARROSA (211) (6.25%), WBLL-1(5.46%), KUKUNA (4.68%) and MILAN (4.68%) amongst common parents.
