Abstract


The present investigation entitled “GENETIC VARIABILITY STUDIES IN WOOD APPLE (FeronialimoniaL.).” was carried out on thirty-two years old Wood apple orchard during the year 2017-2018 at Main Garden Department of Horticulture, Dr.Panjabrao Deshmukh Krishi Vidyapeeth, Akola. The flowering and duration of flowering of studied available germplasm varied from first week of February to first week of March and Three weeks to Nine weeks from date of flowering respectively. The various other morphological characters varied in the following manner. The range of the fruit weight was found in between 190.5 to 389.9 g, range of pulp weight was found in between 103.7 to 262.7 g, pulp percentage was ranged between 51.60 to 66.9, fruit length was ranged between 9.4 to 13.6 cm, fruit diameter was ranged between 10.15 to 15.45, skull weight was ranged between 92 to 138.1,  skull thickness was ranged between 3.17 to 3.87, pulp: skull ratio was ranged between 1.03 to 2.15, number of seeds per 100g pulp was ranged between 67.27 to 214.9, weight of seeds per 100g pulp was ranged between 3.73 to 9.9 (g), seed size was ranged between 2.27 to 3.2 (mm), total soluble solids was ranged between 11.17 to 13.47 (̊Brix), acidity was ranged between 1.12 to 3.69 (%), TSS: acid ratio was ranged between 3.35 to 12.19, total sugar was ranged between 1.82 to 2.17 (%), reducing sugars was ranged between 1.15 to 1.29 (%), non-reducing sugars 0.62 to 0.91(%) and pectin content was ranged between 1.06 to 1.81 (%). The highest genotypic coefficient of variation was observed for TSS: acid ratio, acidity (%), and pulp weight. High GCV is an indication of greater range of variability among the population and the scope of improvement of these characters through simple selection. During present study characters like TSS: acid ratio, acidity, pectin content, number of seeds per 100g pulp, weight of pulp and fruit weight had high heritability values along with the high genetic advance.
