ABSTRACT
The present investigation entitled “Evaluation of Guava cultivars under the subtropical condition of Himachal Pradesh” was carried out on six years old Guava plants at the Horticultural Regional Research Station, Dhaulakuan, (District Sirmour) of Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan during the year 2011-12. The treatments comprised of six varieties of guava (Hybrid-1, Hybrid-3, Allahabad Safeda, Hisar Safeda, L-49 (Sardar) and Lalit). The results showed significant variation in plant height, trunk girth, tree volume, shoot extension, initiation of flowering, duration of flowering, date of full bloom, days to maturity, fruit set, fruit drop, fruit yield, fruit size, fruit weight, TSS, titratable acidity, total sugars ,reducing and non reducing sugars. The highest plant height, trunk girth, shoot extension, duration of flowering and days to maturity reported in Allahabad Safeda. Early flowering and full bloom observed in Hisar Safeda, Hybrid-1 was earliest to mature. Highest tree volume, fruit set, fruit size, fruit weight, TSS, Total sugars, reducing sugars, non-reducing sugars and yield were observed in L-49 (Sardar). Pink flesh colour was observed in Hybrid-1, Hybrid-3 and Lalit, while Allahabad Safeda and L-49 (Sardar) were white fleshed and Hisar Safeda was only variety which shows cream coloured flesh. Round fruit shape was observed in Lalit and Allahabad Safeda, round to oblong in Hybrid-1 and Hybrid-3.The fruits of L-49 (Sardar) were spherical to round while Hisar Safeda exhibit ovate oblong shape. The seeds of Hybrid-3 and Hisar Safeda were soft textured, while Allahabad Safeda, Lalit and Hybrid-1 had medium hard seeds and L-49 (Sardar) had hard seeds. On the basis of overall performance L-49 (Sardar) was found most promising cultivar for subtropical condition of Himachal Pradesh.
