Abstract
A field investigation was conducted during kharif 2025-26 at the
Agricultural Research Station, Prof. Rajendra Singh Rajju Bhaiya University
Naini Prayagraj to characterize 16 maize genotype based on Distinctness,
Uniformity, and Stability (DUS) traits. The experiment was
laid out in an Randomize Block Design with three replications, following
standard spacing and agronomic practices. Observations were recorded on 31 DUS
traits, DUS characters as per the guidelines of PPVFRA (2001) including morphological, leaf, tassel,
ear, kernel and root characters. Leaf traits such as Angle between blade and
stem, Attitude of blade, Anthocyanin colouration of sheath, Tassel traits such
as Time of anthesis, Anthocyanin colouration at base of glume, Anthocyanin
colouration of anthers, Angle between main axis and lateral branches, Attitude
of lateral branches, Density of spikelets, Ear traits such as length, diameter,
shape, Anthocyanin colouration of silks, Number of rows of grains, and position
revealed significant diversity. Kernel traits such as Row arrangement, Shape,
Kernel: 1000 kernel weight (g.)
exhibited long and short ears, which are beneficial for yield. The variation
observed among all the DUS traits in the maize genotype provides a valuable
resource for hybrid development, varietal registration, and trait-based
breeding programs. This diversity supports future research aimed at improving
maize for yield, adaptability, and the identification of superior and protectable
varieties suited to varied agronomic conditions.
