Triticale (Triticosecale) a hybrid of wheat (Triticum) and rye (Secale) is an important cereal crop and has more production as compared to wheat. It has gained importance in fulfilling the increased food demands of the world. For a breeding programme genetic variability and the genetic relationship among genotypes is important. To study this, 70 lines of triticale introduced from CIMMYT were planted in complete block design. Data was recorded for plant height, spike length, number of spikelets per spike, number of grains per spike, number of tillers per meter, grain yields per meter and 1000...
