Abstract
The present investigation entitled “Genetic variability and correlation studies in wood apple (Feronia limonia L.)” was carried out on sixteen years old wood apple orchard during the year 2018-2019 at AICRP on Dryland Agriculture, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. The flowering and duration of flowering of available germplasm varied from first week of February to first week of March and four weeks to eight 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 168.6 to 328.2 g, range of pulp weight was found in between 91.4 to 206.5 g, pulp percentage was ranged between 51.8 to 64.2, fruit length was ranged between 8.4 to 12.8 cm, fruit diameter was ranged between 9.5 to 13.6, shell weight was ranged between 74 to 127.1, shell thickness was ranged between 284 to 3.66, pulp: shell ratio was ranged between 1.13 to 2.0, number of seeds per 100g pulp was ranged between 94.3 to 208.9, weight of seeds per 100g pulp was ranged between 4.06 to 8.18 g, seed size was ranged between 2.06 to 3.23 mm, total soluble solids was ranged between 11.18 to 13.51 0Brix, acidity was ranged between 1.13 to 3.33 %, TSS: acid ratio was ranged between 3.43 to 10.30, total sugar was ranged between 1.84 to 2.15 %, reducing sugars was ranged between 1.17 to 1.28 %, non-reducing sugars 061 to 0.91 % and pectin content was ranged between 1.06 to 1.78 %. The highest genotypic coefficient of variation was observed for TSS: acid ratio, acidity percentage, 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. The correlations among the yield contributing characters weight of pulp, pulp: shell ratio, fruit length and fruit diameter was highly significant. The genotypes DWA-27, DWA-52, DWA-76 and DWA-26 were found promising for future improvement programme. Hence, these genotypes may be given consideration while formulating selection indices for the improvement of yield and sensory qualities in Wood apple.
Description
The study was carried out on Sixteen years old Wood apple orchard during the year 2018-2019 at, AICRP on Dryland Agricuture, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. Where the 25 genotypes are taken for to assess the Genetic variability and correlation in wood apple (Feronia limonia L.) 25 genotypes replicated with 4 times under single plant observation evaluated in Randomized Block Design.
