Genetical Analysis of the Means for Self – Fertilizing Generations in Barley (Hordeum Vulgare L.)

The study included genetical analysis of the means for six generations namely P1, P2, F2, F3, BS1 and BS2 of two crosses in a six row barley (Jezera 1 X Bendicat and Baraka X Arivate) to estimate the genetic parameters that control following traits: plant height grain yield, number of spikes per platnt, spike length, weight of 100 grains and number of grains per spike . The grains of the six generations were planted at Botanical experimental station, college of education, Mosul University in the growing season 2001-2002 using C.R.B.D. with four replications. The rasults indicated that three parameter modol was adequate for number of spikes per plant in the second cross .
