Performance of Exotic Guava (Psidium guajava L.) Germplasm in Humid Sub-Tropics of Meghalaya, India.

Nine exotic accessions (USA) and two standard varieties of guava (Psidum guajava L.) from India were evaluated together for growth. yield and quality attributes under hilly land conditions (30–35% slope) in mid altitudes (1000m) of Meghalaya. Very high degree of variability (CV%) was recorded in respect to number of fruits and fruit yield/tree. Acidity and fruit density followed by fruit weight and tree volume. Number of trees, fruit density, stem girth and tree volume and spread showed positive and significant correlation with yield/tree. All the 16 characters studied had significant differences among genotypes. Accessions No. EC-313009 and EC-313010, were found to be significantly high yielding accessions, with pink pulp and sour taste but showed poor quality. However, the yield performance of EC-313012 and EC-313013 was moderate but quality wise superior among all genotypes. thus identified as promising for mid altitude of Meghalaya.
