Response of Several Varieties of Spraying Wheat to Kinetin

Abstract

A field experiment was carried out during winter season of 2020-2021 at one of the fields of Al-Hamdhiya research station - College of Agriculture - Anbar University - Ramadi district in order to know the response of some growth traits, grain yield and its quality of several varieties of spring wheat to spraying of kinetin. Randomized complete block design (RCBD) according to split plots arrangement at three replications was used. The main plots were occupied by four concentrations of kinetin (0, 50, 100 and 150 mg L-1), whereas the sub-plots were occupied by three varieties of spraying wheat (Sham-6, Iba-99 and Bora). The results showed that the spraying of kinetin at a 100 mg L- 1was significantly superior inthe plant height (101.78 cm), flag leaf area (48.32 cm2), number of grains (57.58 grain spike-1), grain yield (6.542 ton ha-1) and dry gluten percentage (8.91%) compared with other concentrations. Also, Iba-99 variety was significant superior inthe flag leaf area (48.67 cm2), number of grains (62.71 grain spike-1), grain yield (7.185ton ha-1) and wet gluten percentage (28.50%) compared with other varieties.We conclude the possibility of using kinetin to improve the performance of bread wheat crop, as well as the possibility of using the Iba-99 variety on a large scale for agriculture in Iraq.
