Fifteen varieties having a wide range of variability in growth, flowering, fruit, and qualitative traits were studied in Randomized Block Design. Results showed that among the varieties, Allahabad Safeda showed early initiation and ending of flower in rainy season, while, in winter season it was showed by Hisar Safeda. Late flowering initiation and ending was showed by Pant Parbhat in rainy season, whereas, in winter season scattering flower is continous in Lalit, KG Guava, Pant Parbhat and Shweta varieties of guava. KG Guava had the maximum plant height, plant spread, foliage density, fruit length, fruit diameter (width) and fruit weight, while, minimum plant height and spread was found in Banarsi Surkha. Minimun leaf internodes distance was found in KG Guava. Pant Parbhat had maximum internodes distance in branch during both the season and minimum was showed by Barf Khana. Allahabad Safeda had minimum fruit length, fruit diameter (width) and fruit weight. Maximum TSS, TSS:Acid ratios and minimum titratable acidity was observed in Hisar Safead. L-49 had maximum ascorbic acid content during both the seasons. Phyllotaxy in selected varieties found from decussate to opposite type. Leaf shape varied from elliptical, oblong, ovate and trullate type in selected varieties. Mature leaf color varied from green, light green and dark green. In case of fruit shape and surface maximum varieties showed round type of fruit shape and smooth fruit surface, respectively. Pulp color in selected varieties varied from white, creamy-white to pink. In case of fruit skin color, maximum varieties showed yellowish-green color of fruit skin.EnglishThesis
