“…The genetic base of litchi germplasm is quite narrow and presently most of the cultivated varieties are the result of clonal selection or seedling selection [1]. More than 20 litchi varieties are grown in the state, but all matures within 25 days of short span from 3 rd week of May to 2 nd week of June.…”

An investigation was undertaken to study the variability in litchi hybrids developed at BAU, Sabour and their parents with respect to flowering and fruiting behavior. The experiment was carried out in Horticulture garden Bihar Agricultural University, Sabour. A critical analysis of the data for various characters of flowering and fruiting parameters like date of panicle initiation, duration of panicle emergence, flowering duration, flower colour, inflorescence shape and size, maturity period and fruit morphology were taken. Initiation of panicle emergence varied from 21/01/2013 (H-587, H-590) to 17/02/2013 (H-141, Kasba). Duration of anthesis varied from 25/02/2013 (H-517, H-574, H-598 & Early Bedana) to 12/03/2013 (H-70, H-104) and maturity period ranged from 55 to 68 days. Among different genoty [pes. H-73, H-98, H-104, H-510 had fruit shape oval to round similar to their male parent Bedana. Dark red fruit colour of H-70, H-73, H-104, H-566 also resembled Bedana i.e. their male parent. Significant genetic variability was found among the genotypes with respect to flowering characters, thus there is an ample scope for selection of promising genotypes. Thus from above finding it may be concluded that extended period of flowering, fruit set and harvesting span could be achieved through hybridization.

“…Since variability within the breeding material is a pre-requisite for any successful breeding programme, the presence of high variability coupled with high heritability in respect of the traits of interests provide greater scope for further improvement. Such improvement in commercially important traits such as fruit weight, size, quality and yield/plant would contribute a significant prospects and possibilities for increasing production of quality litchi (Gupta et al 2017). The biometrical attributes like variability, heritability and genetic advance are of prime importance in providing information about the relative contribution of various growth and yield related traits to total fruit yield.…”

Genetic variability, heritability and genetic advance in litchi (Litchi chinensis)

et al. 2018

Litchi (Litchi chinensis Sonn.) is one of the most important subtropical fruit crops of the world. Improvement in this crop is constrained by its narrow genetic base, which is a major bottleneck in reaching the desired objectives. Studies on the nature and extent of genetic variability are highly relevant to yield information that can be useful for genetic improvement programmes. In the present study, 22 litchi genotypes including three new varieties were assessed for the variability, heritability and genetic advance and principal component analysis on the basis of 13 quantitative fruit traits. High phenotypic and genotypic coefficients of variation were recorded for pulp weight (32.86 and 31.11%), seed weight (30.56 and 27.93%), peel thickness (25.07 and 20.21%), pulp thickness (24.79 and 22.22%) and fruit weight (22.65 and 21.17%).The heritability and genetic advance were found maximum for fruit yield/plant. High heritability coupled with high genetic advance was recorded for fruit weight, fruit length, fruit width, pulp weight, pulp thickness, seed weight, peel thickness, peel weight, seed width (y-axis) and yield/plant, indicating ample scope of improvement for these traits through selection. From PCA and variability estimates, fruit weight, pulp weight, peel weight, peel thickness, seed weight and seed size were identified as important traits for identifying high-yielding genotypes.
