EVALUATION OF SOME SELECTED GUAVA GENOTYPES

Abstract

This study was carried out during three growing seasons (2014, 2015 and 2016) to investigate some morphological and productivity characteristics of 16 genotypes of seedy guava trees with ten years old, selected from 80 seeded guava trees were selected according to growth, yield and fruit quality attributes, grown in Horticultural Station Orchard, situated at Shandaweel The considered guava trees were raised by seeds. The trees are about 10- years old when this study started, grown in a silt clay loam soil 5x5m apart. Morphological characteristics, flowering, yield and fruit quality. The genotypes were analyzed to select promising guava genotypes for fresh consumption and processing to take part in improvement and propagation programs. The best number of leaf area was found in G. 12, G 11 . Whereas, maximum yield (kg/tree) was in G 10 (65 kg). The highest fruit weight was recorded in G. 13 (151.97), meanwhile it was The lowest in G. 5 (78.39),the seeds number per fruit was significantly higher in guava G. 9 (392.30), meanwhile it was the lowest in G. 5 (112.00) , The low seeds(%) was the best character for fruit quality and associated with genotype No9 (0.90%).The highest values of TSS/acid ratio was obtained by G 15 and G 3 (24.74 and 24.03) and the highest values of V.C were in guava G. 3 (97.35) followed by G. 4 (91.01). The highest total sugars contents (%) was in guava G. 12 (11.37) followed by G. 10 and G. 15 (9.78 and9.72), respectively, it could be recommended with genotypes No. 11,10, 9, 13, 15 &12 the best one was G.10 since it gave the highest fruit production.
