Morphological Characterization and Evaluation Of Snake Gourd Genotypes for Fruit Yield, Yield Attributes and Other Characters

Abstract

The experiment was conducted at the research field of Horticulture Department of Bangabandhu Sheikh Mujibur Raman Agricultural University (BSMRAU) during the period from March to June 2017 to characterize and evaluate the snake gourd genotypes morphologically. In the study, 55 snake gourd genotypes collected from Plant Genetic Resources Centre (PGRC) of Bangladesh Agricultural Research Institute (BARI), Genetics and Plant Breeding Department of BSMRAU, different seed companies and various parts of Bangladesh. The genotypes exhibited 67.3% cylindrical, 21.8% elliptical, 1.8% fusiform, 9.1% ovate shape fruit along with 56.4% green, 18.2% light green, 16.4% dark green and 9.0% white fruit. Seed colour with 38.2% was brown and 83.6% seed shape was elliptical. The fruit length varied from 12 to 54 cm while fruit diameter varied from 3.5 to 5.5 cm. Days to 1st female flower opening ranged between 44 and 62 days and nodes number on female flower initiation was between 12 and 26. Days to 1st fruit harvest varied from 54 to 72 days. The number of fruits/plants ranged from 8.33 to 27, whereas individual fruit weight varied from 90 to 325g. Fruit yield/plant ranged from 1.29 to 7.74 kg. Genotypes were TC01, TC03, TC04, TC05, TC07, TC08 and TC19 identified as early maturity. The genotypes differed significantly in most of the parameters and offer a good scope for selection of parent for crop improvement programme.

Studied the effect of physical and yield attributes on bael (Aegle marmelos Correa) fruits in sodic soil condition

“…fruit weight (0.859-1.964 kg), fruit length (7.63-19.86 cm), fruit circumference (29.66-48.33 cm), number of seed per fruit (8.66-22.66), skull weight (0.177-0.487 kg) and skull thickness (1.83-3.33 mm) in among the collected genotypes. Islam et al (2012) [8] observed that greater variability in morphological and fruit character in collected bael genotypes from different location. Among the fruit characteristics, pulp percent (50.0-76.0), rind percent (17.0-41.1), percent of fibre (1.1-7.1) and percent of seed (0.7-6.4) were found.…”
