Abstract

Evaluation of physical and chemical characteristics of fruit crops has been successfully used for selection of improved cultivars for breeding programs. The study was conducted at typical subtropical conditions in North-West India for evaluating the variability of mango germplasm to conserve the elite ones and identify the superior genotypes based on fruit quality for multiplication and for future crop improvement. Fourteen genotypes were tested for their physiological and chemical characteristics. Randomized complete block design was used and critical difference was used to compare quality characteristics of fourteen mango genotypes. Maximum fruit weight was found in Chausa whereas maximum reducing and total sugars were observed in Malda. Dashehari ranked first in respect of yield per tree, that is, 148.90 kg/tree. Local Selection-I was the earliest to mature. Among all genotypes Chausa, Kala Gola, Hundel and Gola showed tendency towards regular bearing. The Alphonso, Malda and Chausa was identified for superior traits like total soluble solids/acid ratio (TSS/acid ratio); Chausa and Langra Banarasi for high pulp percentage and pulp stone ratio; Rattaul for excellent flavour; ‘Local Selection-I’ for regular bearing and Dashehari for higher yield. These identified genotypes may be good donor in future hybridization programme to evolve the superior varieties.   Key words: Mango, breeding, germplasm, genotype.

Highlights

  • Mango (Mangifera indica L.) is one of the ancient fruits ofIndia and its cultivation appeared to have begin 4000 years ago (Condole, 1984)

  • Being an ancestral home for mango germplasm, India is having more than thousand verities, which are widely distributed in different agro climatic zones (Yadav and Rajan, 1993)

  • The objective of the study was to evaluate morphological characteristics of the mango germplasm and isolate to identify the superior genotype based on fruit quality for future breeding programs

Summary

Introduction

Mango (Mangifera indica L.) is one of the ancient fruits of. India and its cultivation appeared to have begin 4000 years ago (Condole, 1984). It was originated as alloploid and its home was suggested as eastern India extending from Assam to Burma or possibly further in Malay region (Popenoe, 1920). Based on recent findings (Mukherjee, 1997) the centre of origin and diversity of genus. The genus Mangifera consists of 41 species and all the edible cultivars of mango belong to single species M. indica L. Being an ancestral home for mango germplasm, India is having more than thousand verities, which are widely distributed in different agro climatic zones (Yadav and Rajan, 1993)
