Nagai and Kida [11] were the first to observe hybrid vigor in eggplant. The commercial exploitation of heterosis in eggplant is possible due to. Ten genetically diverse parental lines, their 45 hybrids of brinjal obtained Keywords: Dialle cross, brinjal, fruit yield, quality traits, heterosis. through heterosis breeding which is feasible in this crop (kakizaki, ) [25]. Hence reports are available on hybrid vigor in brinjal. Pal and.

Pronounced heterosis over better-parent was observed for Plant height in Bfinjal NidhixArka Kusmakar In the temperate regions, the best prices are normally paid at the beginning of the production season, which makes early cultivars more valuable. Positive heterosis for weight of early fruit was detected for the majority of hybrids, with highest positive scores for hybrids Embu x Melitino, Embu x Florida Market 10 and Embu x Black Beauty.

Brinal values obtained for the yield characteristics in the hybrids depended on the parents involved in the crosses, but all the yield characteristics had some type of genetic gain in the hybrids, compared to the parents. Services on Demand Journal. Heterosis breeding in brinjal. No warranty is given about the accuracy of the copy.

Users should refer to the original published version of the material for the full abstract. Heterosis and genetic architecture of leaf and yield characters in eggplant.

The magnitude of the heterosis depended on the genotypes used. The heferosis fruit weight, independent of the heterosis and heterobeltiosis values found, showed small difference from the established standard in the market commercial F hybrid.

study of heterosis in brinjal (Solanum melongena L.)

In view of the high heterosis and or heterobeltiosis values shown for the different characteristics, the importance of the non-additive genetic effects in their expression can be inferred. Significant levels of heterosis were detected for all the traits studied. Each experimental plot consisted of 10 plants heterowis was spaced at 1. How to cite this article. However, users may print, download, or email articles for individual use. However, it may be useful in brinal Southern region when planting is carried out soon after winter.

Data brijnal quantitative characters were recorded and percent better-parent and standard heterosis were determined. II – Notes on the brinjal and bitter gourd. Pal and SinghOdland and NollIkuta and Monteiro also found significant heterosis results for this trait.

The eggplant Solanum melongena L. On the other hand, the heterobeltiosis values were mostly negative, though the hybrid Embu x Melitino was positive and outstanding Table III.

Fourteen harvests were carried out, at seven day intervals, during a three and a half month period. Cultivars Hteerosis and B were parentals in those hybrids.

A randomized complete block design with three replications was used. Estudos Recentes sobre Brinmal. The F1 hybrids used were: However, since it does not take into account the yield of slightly inferior but still commercially viable fruits, this criterium cannot be used as the only selection method.

EBSCOhost | | Studies on Heterosis in Brinjal (Solanum melongena L.).

For abbreviations see Table II. Hybrid vigour and combining ability in eggplants. Average early fruit weight.


This abstract may be abridged. The hybrids displaying high heterosis also had high heterobeltiosis Table II.

The commercial valorization of a crop, in terms of product quality, is dependent on its capacity to concentrate the greatest number of fruit within the market standards.

Heterosis and combining ability in eggplant. First class fruit yield is a production characteristic which allows phenotypic selection of superior genotypes, in a screening process.

All hybrids showed positive heterosis and heterobeltiosis for total yield Table II. Thus, it is presumed that the establishment of a population with a wide genetic base, using recurrent selection methods for increasing combining ability along with reciprocal recurrent selection, hterosis lead to future new lines which result in hybrids superior to those hetegosis.

Significant heterosis relative to the parental means was detected for all traits studied. All the other hybrids showed positive values.

When the yield characteristics are used as assessment criteria, it is desirable that the heterosis and heterobeltiosis levels, shown in the hybrid combinations, be as high geterosis possible. Following the same tendency of the early assessment, the mean fruit weight had positive heterosis for the majority of the hybrids. Table I – Description of the eggplant parentals.
