Microsatellite marker-based characterization of waxy maize inbreds for their utilization in hybrid breeding.

ABSTRACT: Waxy corn possesses 95-100% amylopectin, compared to 70-75% in normal maize, owing to mutation in Wx gene encoding a granule-bound starch synthase I. Amylopectin is used as an ingredient in textile, adhesive and paper industries. Further, waxy green cob is popular as breakfast item in South Asia and an important constituent of diet in north-eastern states of India as well. We developed a series of waxy inbreds from diverse exotic sources and through introgression breeding. To characterize and unravel the genetic relationships, 24 diverse waxy inbreds were analysed using 77 SSRs distributed throughout the genome. The study generated a total of 203 polymorphic alleles, with a mean of 2.69 alleles per locus. A total of nine unique and 20 rare alleles were detected. The polymorphism inf
