Fruit characterization of different avocado (Persea americana Mill.) genotypes in eastern mid-hills of Nepal

Abstract

The total of thirteen different avocado (Persea americana Mill.) genotypes were collected for evaluating the fruit characteristics in the laboratory of Agricultural Research Station, Pakhribas during November 2017. The fully matured fruits from the farmer's field at Patle, Dhankuta were collected. The criteria for selecting the genotypes were fruit weight, fruit length, fruit diameter, seed weight, pulp weight, pulp to fruit ratio and the seed weight percentage. The result suggests the potentiality of the genotypes PAKAV002 and PAKAV010 in most of the evaluated characters as compared to the tested genotypes. The genotypes PAKAV008 and PAKAV007 were disliked as they have 32.59% and 28.39% of seed weight to the total fruit weight. The genotypes PAKAV002 and PAKAV010 had the average fruit weight ranging (307.1 g and 346.8 g), maximum of pulp to fruit ratio 62.34% and 56.97%. Similarly, genotypes PAKAV010 (11.425%), PAKAV013 (11.96%) and PAKAV002 (14.47%) had low seed weight to the total fruit weight which is regarded important factor for avocado selection and evaluation. This result shows that the genotypes PAKAV002 and PAKAV010 should be further evaluated for fruit characteristics and the quality.

Morpho-physico-biochemical characterisation of Avocado (Persea americana) for selection of elite types

“…The maximum pulp weight was observed in MZU-HAMP-AVS-1 (267.97 g), followed by MZU-HAMP-AVS-18 (257.13 g), MZU-HAMP-AVS-7 (257.23 g), and MZU-HAMP-AVS-21 (251.88 g), while, the MZU-HAMP-AVS-3 recorded the lowest (152.30 g). Poudel et al (2018) also obtained similar findings as that of our results in avocado.…”

“…Like other parameters of peel, maximum pulp:peel ratio was observed in MZU-HAMP-AVS-18 (5.47) which was significantly superior to all the accessions except MZU-HAMP-AVS-17 (5.36), while, the lowest was observed in MZU-HAMP-AVS-12 (2.96). Poudel et al (2018) also obtained similar results in avocado with respect to pulp:peel ratio.…”

“…Although a number of research work has been carried out on avocado characterization throughout the globe (Nkansah et al 2013, Ge et al 2017, Abraham et al 2018, Poudel et al 2018, Juma et al 2020, Augustine et al 2021, Juma et al 2021, Ranjitha et al 2021, however, no research work has been carried out in the northeast India to assess the diversity of avocado. Hence, the present study was carried out to evaluate the elite types of avocado by using morpho-physico-biochemical characters.…”

Identification of Suitable Budwood Source through Quality Assessment of Avocado (Persea americana Mill.)

“…These discrepancies could be linked to the variety's genetic makeup and geographical location. According to Poudel et al [20], low seed weight suggests an increased amount of pulp around the seed. Even though, there was no significant difference between treatment H and I, they had distinct morphological differences.…”

“…Poudel et al [20] concluded that pulp weight is one of the most critical parameters in assessing avocado fruit quality. As a result, treatment F is of superior quality than the other types; this could be related to the variety's genetic makeup.…”
