Standardization of seed, rootstock and plant standards of lasoda (Cordia myxa L.) for commercial orcharding in India

Abstract

Aim: The present study was conducted to develop the planting material standards of lasoda cultivar ‘Thar Bold’ for commercial orcharding in India. Methodology: The ripe fruits at pink colour appearance from mother tree of lasoda ‘Thar Bold’ were collected from Experimental Block-I after 75+5 days after fruit set during last week of May- first week of June months for raising of seedlings. Fruits and seeds were categorized based on size and weight and accordingly seeds sown in field bed and root trainers. At two true leaf stage, the seedlings were shifted in polybags for working out seed and rootstock standards. Further, to develop the planting material standards, the scion buds of current season’s growth were collected and budded during third week of May, June and July. The standards were prepared on the basis of all possible traits of the interest. Results: Under the present study, planting material standards of lasoda were developed with following prerequisites: ripened fresh fruits should have diameter > 1.5 cm and fruit weight > 6 g with seed germination > 60 %; buddable seedlings/ rootstock of 9-12 months should have about 35-40 cm height and 0.8-1.0 cm girth; budding should be done during May-June months; at 90 days of budding, plants with sprouts length ≥ 50 cm and diameter ≥ 0.5 cm should be good for field planting in the same season. Interpretation: The developed standards of lasoda would be highly useful for conservation of elite type and large scale multiplication of quality planting material for commercial orcharding in the country.
