Abstract/ Executive Summary:

Evaluation of Eight Litchi !ines namely, LC-001, LC-002, LC-003, LC-004, LC-005, LC-006, LC-007 and LC-008 were tried at Regional Horticultural Research Station, BARI, Chapainawabganj. All the lines grew, but only five lines fruited. The line LC-001 as found to be tallest (621.6 em) while the line LC-004 was the shortest (241-6 em). The lines differed little in respect of time of flower opening. The line LC-001 was the earliest (40.00 days) to initiate flowering while the line LC-004 was the latest (47.00 days) in this respect. The line LC-006 had the highest percentage of hermaphrodite flowers (25%) with highest numbers of fruit (786.6) per plant. And the line LC-004 had the lowest percentage (15%) of hermaphrodite flower with moderate number of fruits (516.6) per plant. The line LC-001 was found the earliest (81.6 days) while the highest yielder line was the latest (93.33 days) regarding time of harvesting. Mean fruit weight of litchi was the highest in the line LC-006 with moderate stone/pulp ratio, while the line LC-004 produced 13.94 g of fruit weight with highest stone/pulp ratio. The highest TSS was noticed in the line LC-003 (19.42%). while lowest in LC-006 (15.53%).

Location: Regional Horticultural Research Station at Chapainawabganj.

Start Date: 14-08-1994

End Date: 00-00-0000

Program Area: Variety and Species

Commodity: Litchi

Objectives:

To assess the performance of eight imported litchi lines from far reaching country (Australia).

Methodology:

Eight lines of litchi namely, LC-001, LC-002, LC-003, LC-004, LC-OOb, LC-007 and LC-008 were the materials for the study. All of the liens were procured from Australia. Grafted seedling of eight litchi lines belonging to Litchi chinensis Sonn were transplanted on 14 August 1994 at Regional Horticultural Research Station at Chapainawabganj. After deep ripping with three seedling of each line were transplanted 6m by 6m spacing in a Randomized block design as suggested by Galan Sauco (1990). All the seeding received manure and fertilization practice since the period of transplantation. The practice was followed every year with increasing amounts of nutrients. Farm yard manure, calcium ammonium nitrate, superphosphate, murate of potash at the rate of 10-20, 0.3-1.00, 0.2-0.6 and 0.05-0.15 kg/plant applied while the plants were of 1-3 years old. In the fourth of sixth year, the plants of the respective litchi line were fertilized with 25-40 kg of farm yard manure, 1-2 kg of calcium ammonium nitrate, 0.75-1.25 kg of superphosphate and 0.20-0.30 kg of murate of potash per plant. The whole amount of each manure and fertilizers were divided into two installment. The first installment was applied at the beginning of summer season followed by irrigation. And the other installment applied after the rainy season. Manure and fertilization application was withheld during cold months to prevent vegetative flushing. Plants were weeded, mulched and irrigated in order to keep them in good growing condition. During the 2-4 years, all side shoots up to 0.8 m -1.0 m removed from the plants to keep free from low hanging branches. During the year 1999-2000, a study was undertaken to judge the plants of different litchi lines from the point of view of growth attained by them as well as flowering and fruiting behavior showed by the different plants of line. Among those that were available for study, they were the plants of the line LC-001, LC-003, LC-004, LC-005 and LC- 006, at the time of study the plants were five years old.

Achievement/Findings:

Different lines of litchi under the study showed variation in their flesh and skin colour. The line LC-001, LC-003 and LC-005 had milky white coloured flesh with greenish bright and dull red skin colur. The line LC-004 and LC-006 produced flesh of white and waxy colour with light and bright red coloured skin.
