Division of Fruit Crops

 

The Division of Fruit Crops was started with one Senior Research Assistant transferred from the ICAR headquarters in February, 1968. The Division was also selected as a main centre for grapes under AICRP and some staff of this project also joined the Division.  Efforts were made during the initial period to procure germplasm of various fruits for improvement work which resulted in introduction of many accessions of grapes and strawberry from USA, USSR, Japan, Italy, Holland and Canada. Over the years, the Division has grown into a major one encompassing work on improvement and production technology of mango, grapes, pineapple, guava, papaya, pomegranate, ber, annona and citrus.

 

Mandate

  • Carry out basic and strategic research for enhancing productivity, quality and utility of fruit crops in tropical agro-climatic zones of India.
  • Act as Repository of fruit genetic resources and their management.
  • Transfer of technologies and study their impact.
  • Conduct teaching and training programmes for development of human resources.
  • Use ICT in scientific information and knowledge.

 

Thrust areas (Current)

  • Resistance breeding for biotic and abiotic stress – papaya PRSV, mango anthracnose, passion fruit wilt, pomegranate bacterial nodal blight.
  • Crop regulation studies in coloured seedless grapes, pomegranate and Annona.
  • Integrated approaches for rootstock, canopy architecture, high density, water and nutrient productivity and fertigation issues.

Achievements

Crop Improvement

Mango

The total collection in mango stands at 538. Evaluation of germplasm showed that the variety Sora had the maximum fruit weight (1166 g) followed by the variety Tenneru (945 g). It was found to be minimum in Kalakai (88 g). Screening of the 32 mango varieties for fruit fly showed that the varieties Bhuto Bombay and Virudhunagar when exposed to fruit fly under artificial conditions did not record any infestation. The varieties Gopal Bhog, Bhutto Bombay, Manipur, Manibhatta Appe and Virudhunagar did not show any stone weevil infestation.

Guava

The total collection in guava stands at 76 including five species.

Sapota

Germplasm of 33 Sapota accessions are being maintained in the field. An open pollinated seedling progeny of Cricket Ball (no.63) isolated has been multiplied by grafted and 20 grafts are planted in field for further evaluation.

Jamun

Nine accessions of Jamun were collected from various sources like KRCC, Arabhavi (6 accessions), CISH, Lucknow (2 accessions) and one Konkan Bahadoli from Regional Fruit Research Station, Vengurle.

Underutilized fruits

At present, 42 accessions of underutilized fruits are being maintained. A total of 19 accessions in jackfruit and 9 in pummelo have been evaluated. The accession     G-65 continued to be superior in jackfruit. In pummelo, a pink pulped accession has also been found good with respect to quality.

Papaya

At present 32 accessions including two species are being maintained. The evaluation of the intergeneric hybrid progenies for PRSV, a few progenies are showing tolerance in addition to good fruit quality.

Papaya-drought tolerance

 As pollen germination under stress is one of the indirect ways of assessing drought tolerance, different accessions of Carica papaya were evaluated by artificial pollen germination. Amongst the 32 accessions tried, V. cauliflora, Dwarf Lilly and CO6 recorded pollen germination over 50 per cent.

 

Pomegranate

Two accessions of pomegranate have been introduced from Afghanistan one with acidic taste and the other with sweet and seedlings raised from them. Screening of nearly 500 progenies of Daru, Nana (Yellow) and Nana (Red) was taken up and found that Daru had highest per cent (51.41) of population resistant to BBP. Nearly 5000 seedlings of Daru, Nana and OPs of Bhagwa were raised for evaluation against BBP. Two hybrids of DF x N with less spines were identified as a source of breeding lines.

Strawberry

Sixty six accessions were added. Three hundred forty four putative disease tolerant hybrids with various degree of tolerance to different fungal diseases (based on one season of screening/field survival) are being furthered for rigorous screening.

Passion fruit

A total of twelve genotypes are being maintained.

Production Technology

Canopy architecture (Mango, grapes and fig)

In the field trial involving planting densities of 1111 (3m x 3m), 400 (5m x 5m) and 178 (7.5m x 7.5m) ‘Alphonso’ trees / ha. on ‘Vellaikulumban’ and ‘Olour’ rootstocks with or without the application of paclobutrazol, the vegetative growth parameters were lower for paclobutrazol applied trees and those on Vellaikulamban rootstock. Flowering was more at wider spacing and on trees that received paclobutrazol treatments, the trend being more pronounced with Olour rootstock. The highest fruit yield of 14.63 t / ha during the twelfth orchard year was obtained with 3m X 3m spacing using Olour rootstock and 1.25 g paclobutrazol / tree compared control at 10m X 10m spacing (100 trees / ha) on random Totapuri rootstock without paclobutrazol yielding only 4.64 t/ha. The treatment combinations did not significantly affect fruit quality, though acidity tended to be more for closer spacing. Paclobutrazol residues in surface soil (0-15 cm) samples collected from under mango tree canopy at the time of fruit harvest were in the range of 0.044 to 1.145 mg / kg for the lower application rate (0.125 g / tree / year of age) and in the range of 0.096 – 1.88 mg / kg for the higher application rate (0.25 g / tree / year of age), but fruit samples from all the treatment combinations were free of any paclobutrazol residues.
