Abstract
Pigeonpea (Cajanus cajan (L.) of Fabaceae family belongs to
genus Cajanus usually grown in semi-arid tropics of Asia and Oceania, Africa and
America. This crop has been a best source for improving food and soil quality
amongst farmers. However, its seed have been always questioned for purity. This
problem is managed by using polymorphic SSR markers. In present study, a DNA
fingerprints generated by seven SSR markers and hybrid testing is performed on
Pigeonpea test samples along with parental lines. The seed samples of pigeonpea were
germinated in laboratory and three week old leaves samples were used for DNA
isolation by CTAB method. A total of 9 alleles were observed in three test samples
using three primers out of seven primers. The screening of the allelic data associated
with the three cultivated varieties, revealed markers (CcM0246) displayed unique
allelic profiles for one variety. Yet, the genetic fingerprinting data is not well resolved
to potentially distinguished two bands of hybrid that are merely of 4-8 bp to confirm
hybrid testing of seed. Hybrid Testing of pigeonpea may be confirmed including more
SSR primers prepared from genomic DNA of pigeonpea.
