Abstract:

The present study was conducted to study the effect of depth of sowing on seedling emergence, and correlation with coleoptile length in advance lines of wheat. The experimental material comprised of 60 wheat genotypes including certain advance lines and released varieties; and was carried out for two consecutive season viz. 2016-17 and 2017-18. These genotypes were categorised into three different coleoptile length groups i.e. short (2.5-4.5 cm), medium (4.6-6.5 cm) and long (6.6-9 cm) coleoptile length on the basis of observation in laboratory. All genotypes were sown at three different depths of 5cm, 7.5cm and 10 cm and replicated twice. The study revealed that the short and medium coleoptile length genotypes had less variation in emergence at all depths whereas the longer coleoptile length genotypes had significantly better field emergence. Coleoptile length was directly proportional to seedling shoot length i.e. short, medium and long coleoptile classes had an average coleoptile length of 7.12 cm, 8.87 cm, and 12.60 cm respectively. Longer coleoptile length class genotypes also had higher SVI I and SVI II i.e. short, medium and long coleoptile classes had an average SV I value of 2051.8, 2198.11 and 2752.33 and SV II value of 42.3, 55.57 and 72.8 respectively. Larger coleoptile length was also in accordance with the higher root surface area, root volume and number of forks which provide genotypes early seedling vigour in stress conditions.
