dc.description.abstractThe present study entitled “Effect of genotypic variation and seeding practices on coronal root formation in wheat” was carried out to explore diversity in coronal root parameters (number of coronal roots per tillers, effective anchoring length (cm), effective anchoring thickness (mm), angle with respect to vertical root axis and first internodal length (cm) of coronal roots) among genotypes under different seeding rates and seeding depths. The study was conducted at the experimental area of Wheat section, Department of Plant Breeding and Genetics, Punjab Agricultural University, Ludhiana during two successive growing seasons of 2016-17 and 2017-18. In first growing season, 28 genotypes under different tillage systems (normal, deep sowing and zero tillage) were sown. On basis of coronal root parameters and morphological parameters 18 genotypes were selected to be sown in second growing season. In 2017-18 eighteen genotypes were sown in nine seeding conditions representing combination of 3 seeding depths (2 cm, 5 cm, 8 cm) and 3 seeding rates (4g/0.64 m2, 8g/0.64 m2, 16g/0.64 m2). Coronal root parameters were recorded at vegetative and anthesis stage. Coronal roots performed best under 2 cm and 5 cm seeding depth with 4g seeding rate. Based on the performance of genotypes under different seeding practices and lodging scores BWL 1771, HD 2967, BWL 3473, PBW 723, HD 3086 can be regarded as lodging tolerant genotypes on the basis of coronal root parameters.en_US
