dc.description.abstractABSTRACT The present investigation entitled “Characterizing some guava (Psidium guajava L.) cultivars and hybrids” was carried out on eight years old stool layered nine guava cultivars and hybrids namely Punjab Hybrid-1, Punjab Hybrid-2, CISH-G-1, Lalit, Allahabad Safeda, CISH-G-4, Lucknow-49, Hisar Safeda and Hisar Surkha during the year 2016-17 and 2017-18 in RHR&TS, Dhaulakuan, Sirmour (H.P.), India. The experiment was laid out in a Randomized Block Design. These cultivars and hybrids were evaluated for their growth, foliage, floral, fruit, yield, biochemical and seed characters. The attitude of branches was observed to vary from erect to spreading to drooping. The anthocyanin colouration of young leaf was absent in Punjab Hybrid-2, Lucknow-49 and Hisar Safeda and present in rest of the cultivars and hybrids. Variation in leaf shape i.e. obtrullate, oblong and ovate; leaf apex shape i.e. apiculate and obtuse; leaf base shape i.e. rounded, obtuse and cordate were also observed. The flower initiation was found to be earliest in Lalit and Allahabad Safeda during both the years, whereas, CISH-G-1 and Hisar Safeda were the last. Fruit size and weight were observed maximum in Lalit which recorded highest fruit yield per tree but lowest yield efficiency. The fruit shape was observed to be ovate with pointed shape at stalk end in Punjab Hybrid-1, CISHG-4 and Lucknow-49, whereas in others were round in shape. The smooth fruit surface was observed in Punjab Hybrid-1, Allahabad Safeda and Hisar Surkha with longitudinal ridges in Lucknow-49, CISH-G-4 and Allahabad Safeda; longitudinal grooves in CISH-G-1, Lalit and Allahabad Safeda; conspicuous ridged collar around calyx cavity in Hisar Safeda. Flesh colour varied from yellow-white to greyed-yellow to orange-white to greyed-red. Maximum TSS, total sugars and reducing sugars were recorded in Hisar Safeda with minimum acidity. Lucknow-49 was observed to have minimum number of seeds. Fruits were found to be soft seeded in Hisar Surkha, CISH-G-1, Lalit and Allahabada Safeda were medium seeded and rest were hard seeded. From the present study it can be concluded that the development of descriptors will facilitate true identification and DUS testing of guava genotypes.en_US
