Abstract:

Punjab 2011 is a high yielding rust, lodging and heat tolerant wheat variety developed by Wheat Research Institute, Ayub Agricultural Research Institute, Faisalabad, Pakistan. It is a local cross developed through hybridization between two wheat genotypes i.e., AMSEL / ATTILA and INQ.91/PEW’S’. F2 to F6 generations of this cross were advanced by modified bulk pedigree method during 2000-05. The variety was tested for multilocation trials under different agro-climatic conditions during 2007-08 and under national uniform trial during two consecutive years, 2008-09 and 2009-10. The variety was finally approved for cultivation in 2011 by Punjab Seed Council. The plant type of Punjab-2011 is semi erect with 110-115 cm height along with yellow coloured straw. Its flag leaf attitude is semi erect and auricle colour is white. This variety has tapering head shape with 10-11 cm length having 19-21 spikelets per spike. The heads of variety emerges from flag leaf between 100-110 days and matures within 144- 150 days. This variety has high tillering capacity (480 tillers/m2). The grains of this variety is ovate, medium and amber in colour. Its grain yield potential is 6893 kg per hectare and average yield is 4260 kg per hectare under different agro-ecological zones. This variety moderately resistant to Ug 99 race of stem rust and also proved resistant to prevailing races of leaf and yellow rusts. The release of this variety may reduce the chances of epidemic rusts especially stem rust and high temperature appeared at grain filling stage.
