Abstract

In order to determine the relationship between yields and some morphological traits, as well as important traits that affect grain yield in TRITICALE, a field experiment was conducted at Cereal Research Farm, Seed and Plant Improvement Institute, Karajin 2000. Fifty lines and cultiyars were evaluated in an. Alpha Lattice design with two replications. Grain yield was positively correlated with biological yield, number of spikes per plant, number of seeds per spike, Harvest Index and date of maturity. A STEPWISE REGRESSION analysis was also carried out for grain yield (dependent variable) and other characters. PATH ANALYSIS showed that number of spikes per plant and number of seeds per spike exerted the most direct effects on grain yield. On the basis of these results, it is suggested that criteria such as biological yield, Harvest Index, number of spikes per plant, number of seeds per spike, 1000 seed weight and spike length could be considered as effective criteria for selecting towards grain yield improvement in TRITICALE.
