Genetics of quantitative characters in six-rowed Barley over environments

Abstract

The experimental material consisted of parents, F1 and F2 generations of a 10 x 10 half diallel set. The material was laid out in RBO with 3 replications in three environments namely, early, normal and late sowings referred to as E1, E2 and E3 respectively. The ten parents included were BG 105, BG 25, BH 28, BL 2, DL 100, DL 165, DL 88, K 125, RD 103 and RD 728. Each plot consisted of a single 4m row in parental and F1 generations, and 4 rows of 4m each in F2 generation with a row to row spacing of 30 cm and plant to plant spacing of 10 cm. Ten competitive random plants in parents and F1s and 25 plants in each of F2 progenies, were selected for recording observations on nine characters under each environment. The mean of each plot was used for statistical analysis. The genetical analysis for each character was conducted following Hayman [1].
