Improvement of subtropical plum through hybridization
Studies on the improvement of subtropical plum through hybridization were carried out in the northern plains of Punjab (India) with the objective to develop superior plum cultivars adapted to the Amritsar growing conditions. Intraspecific hybridization involved a number of genotypes of indigenous plum and the introduced cultivar 'Satluj Purple'. Interspecific hybridization involved crossing the plum genotypes 'Alu Bokhara Amritsari' and 'Alu Bokhara Peshawari' with peach and almond as male parents. Fruit set varied highly as particularly the interspecific hybridizations suffered serious fruit drop and only a few fruits were retained. The fruit set of the crosses varied among the mother parents.
