Agro-morphological and seed trait characterization of wheat genotypes is a prerequisite for varietal
identification, DUS testing, and maintenance of genetic purity in seed production systems. The present investigation
was carried out at ICAR–IARI Regional Station, Indore, Madhya Pradesh, during the rabi seasons of 2022–23
and 2023–24 to characterize eight promising wheat genotypes along with two check varieties (DBW-187 and HD2967). The experiment was laid out in a randomized complete block design with three replications. Significant
variation was observed among genotypes for major quantitative traits, including plant height, days to heading,
peduncle length, ear length, awn length, and thousand grain weight, while most qualitative seed and plant descriptors
remained stable across years. Absence of coleoptile anthocyanin coloration, uniform amber grain colour, and
consistent awn presence contributed to varietal distinctness and seed identity. Early heading and maturity were
recorded in genotypes 22BRHI3304 and 22BRHI3305, whereas 2889/2139 and 22BRDP5001 were late maturing.
The stability of qualitative traits coupled with significant differences in yield-related seed traits highlights the suitability
of these genotypes for DUS testing and seed certification. The study underscores the importance of integrating
agro-morphological and seed characters for varietal registration, seed purity maintenance, and wheat improvement
under Central Indian conditions.
