Characterization of bread wheat (Triticum aestivum L.) genotypes through seed morphology

Abstract

The investigation was undertaken at the Department of Seed Science and Technology, Junagadh Agricultural University, Junagadh, during rabi 2017-18 to characterize 30 bread wheat genotypes released for general cultivation in Gujarat at state level as well as at the National level in central India based on the chemical tests. Based on the seed colour, all the 30 genotypes were having amber colour seed. On the basis of seed shape, genotypes were classified into ovate (12 genotypes), oblong (14 genotypes), elliptical (2 genotypes) and round (2 genotypes). On the basis of seed size, genotypes were grouped into medium seed size (5 genotypes), bold seed size (17 genotypes) and very bold seed size (8 genotypes). On the basis of seed hardness, genotypes were grouped into hard (20 genotypes) and semi-hard (10 genotypes). Based on the seed germ width, genotypes were grouped into medium (20 genotypes), wide (6 genotypes) and narrow (4 genotypes) seed germ width types. The genotypes were grouped based on the seed crease into three groups, as medium (14 genotypes), shallow (13 genotypes) and deep (3 genotypes) seed crease types. Based on the brush hair length, genotypes were grouped as short (18 genotypes), medium (9 genotypes) and long (3 genotypes) brush hair length types.
