Agro-morphological and molecular characterization of barley (Hordeum vulgare L.) (original) (raw)

Genetic diversity among twenty eight elite barley genotypes (Hordeum vulgare L.) grown in Bangladesh Agricultural Research Institute (BARI), Joydevpur, Bangladesh was assessed using agro-morphological characters and randomly amplified polymorphic DNA (RAPD) markers. Significant variation was observed among all the genotypes for the characters viz. days to heading (DH), days to maturity (DM), plant height (PH), number of tillers per plant (NTP), length of seed (LSD), breadth of seed (BSD), length of spike (LSP), number of grains per spike (NGS), 1000-seed weight (TSW), yield per plant (YPL), yield per plot (YPT) and yield per ha (YH) studied. High genotypic co-efficient of variation (GCV) was observed for NTP followed by NGS, YPL and YH. High heritability with medium genetic advance in percent of mean was observed for PH, LSD, BSD, LSP and YPL. Path co-efficient analysis showed that YPT, DH and YPL had more contribution on YH in positive direction as compare to other characters. The ...
