Sažetak

DNK je ekstrahovana iz uzoraka krvi lokalnih linija pilića: Bandara, Gimmizah, i njihovih meleza (Bandara x Gimmizah i Gimmizah x Bandara). RAPD-PCR tehnika je korišćena za otkrivanje genetskih sličnosti, deljenih traka (band sharing - BS) među hibridima-melezima i njihovim roditeljima korišćenjem prajmera devet kratkih oligonukleiotida. Genetska sličnost izražena kao BS vrednosti je izračunata u granicama od 68 do 91%. Bandara muški pilići sa kokicama Gimmizah su pokazali pozitivni heterozis u uzrastu of 8 nedelja. Međutim, dokazi dobijeni u ovom istraživanju ukazuju da se ukrštanjem lokalnih linija može veoma brzo poboljšati telesna masa potomstva tokom komercijalnog uzrasta. Ovo istraživanje održava sposobnost RAPD-PCR za utvrđivanje povezanosti između genetske sličnosti ispoljenu kroz BS vrednosti i heterozis (hibridni vigor).
