Nagai and Kida  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, ) . Hence reports are available on hybrid vigor in brinjal. Pal and.

Each experimental plot consisted of 10 plants and was spaced at 1.
No warranty is given about the accuracy of the copy. Services on Demand Journal. 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.
Fruit characteristics are very important in eggplant breeding, as quality in vegetables is as much or beinjal important than quantity Paterniani, Pronounced heterosis over better-parent was observed for Plant height in Arka NidhixArka Kusmakar The heterosis magnitude indicates that the use of F1 hybrid plants improves this characteristic.
The magnitude of the heterosis depended on the genotypes used. Hybrid vigour and combining ability in eggplants. Fourteen harvests were carried out, at seven day intervals, during a three and a half heteeosis period. Send correspondence to J. II – Notes on the brinjal and bitter gourd. Expression of heterosis for productive traits hsterosis F1 eggplant Solanum melongena L.
In the temperate neterosis, the best prices are normally paid at the beginning of the production season, which makes early cultivars more valuable. The eggplant Solanum melongena L. Under Brazilian conditions, early yield is not a limiting trait. However, it may be useful in the Southern region when planting is carried out soon after winter.
Users should refer to the brimjal published version of the material for the full abstract. Throughout the last century, Brinjal breeding has been based on various standard methods, which has ultimately resulted in the development of improved tomato cultivars and hybrids having high quality and yield attributes.
The seven cultivars, two lines, 18 F1 hybrids and two commercial hybrids were tested in a randomized complete block design with three replications at the experimental field of the ESAL campus, Lavras, MG, from February to October All hybrids showed positive heterosis and heterobeltiosis for total yield Table II.
A randomized complete block design with three replications was used. 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 for different quantitative traits in brinjal (Solanum melongena L
Cultivars Embu and B were parentals in those hybrids. All the other hybrids showed positive values. Remote access to EBSCO’s databases is permitted to patrons of subscribing institutions accessing from remote locations for personal, non-commercial use. The heterosis and heterobeltiosis for hybrid early yield were also positive Table II. Heterobeltiosis values were mostly negative. The F1 hybrids used were: Most authors recommend the commercial use of eggplant hybrids because of heterosis for fruit yield traits Monteiro, Seeds from three of the 20 experimental hybrids obtained did not germinate.
The high degree of heterosis in eggplants has been reported in several studies, in the Brazilian and world-wide literature Monteiro, ; Noda, ; Dixit jeterosis al.

Pal and SinghOdland and NollIkuta and Monteiro also found significant heterosis results for this trait. Following the same tendency of the early assessment, the mean fruit weight had positive heterosis for the majority of the hybrids. This abstract may be abridged. The mean fruit weight, independent of the heterosis and heterobeltiosis values found, showed small difference from the established standard in the market commercial F hybrid.
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 as possible. Significant levels of heterosis were detected for all the traits studied. Estudos Recentes sobre Heterose.

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. Table I – Description of the eggplant parentals.
Average early fruit weight. 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, will lead to future new lines which result in hybrids superior to those studied.
The fruits classified as first class corresponded to the official commercial classification, classes Extra AA and Extra A.
