Abstract
morphological descriptors with the objective to identify key diagnostic characters of the genotypes.
A set of 24 pearl millet genotypes (7 hybrids, 17 parental lines) was evaluated in randomized block design
(RBD) with three replications at Hisar and RRS Bawal under irrigated and rainfed conditions, respectively
during kharif 2011. Observations were recorded for 34 morphological, seed and yield characters and
considerable amount of variation was found in material under study. All the genotypes were classified in
different groups for each character. Majority of the qualitative/morphological characters found to be
dominant in the hybrids were contributed by the male parent. Bristles (present/absent), nodal pubescence,
seed covering were found as dominant characters.
Nodal pubescence, nodal pigmentation, spike shape, spike density, spike tip sterility, sheath
pubescence and spikelet glum colour distinguished all the 24 genotypes by assigning them key diagnostic
features that would certainly help the plant breeders, seed growers and also seed certification agencies to
use these diagnostic characters. Hybrids HHB 216, HHB 226, HHB 117 could be differentiated by bristle
length, spikelet glume colour and spike tip sterility.
