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.

Fruit characteristics are very important in eggplant breeding, as quality in vegetables is as much or more important than quantity Paterniani, Hybrid vigour and combining ability in eggplants. Significant levels of heterosis were detected for all the heteroosis studied.
Fourteen harvests were carried out, at seven day hetersois, during a three and a half month period. Expression of heterosis for productive traits in F1 eggplant Solanum melongena L. Throughout the last century, Brinjal breeding has been based on various standard methods, which has ultimately resulted in the heterosks of improved tomato cultivars and hybrids having high quality and yield attributes. No warranty is given about the accuracy of the copy. 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.
However, users may print, download, or email articles for individual use. Most authors recommend the commercial use of brinjzl hybrids because of heterosis for fruit yield traits Monteiro, On the other hand, the Santa Genebra x Melitino hybrid displayed a negative heterobeltiosis value. Monteiro and Noda also reached this conclusion. Heterosis and genetic architecture of leaf and yield characters in eggplant.
Each experimental plot consisted of 10 plants and was spaced at 1. Data on heterodis characters were recorded and percent better-parent and standard heterosis were determined.

The heterosis and brijnal for hybrid early yield were also positive Table II. 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.
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.
The fruits classified as first class corresponded heeterosis the official commercial classification, classes Extra AA and Extra A. How to cite this article. The use of F1 hybrids in eggplants provided a quick and practical way of obtaining greater early yields.
A randomized complete block design with three replications was used. All hybrids showed positive heterosis and heterobeltiosis for total yield Table II. Services on Demand Journal. The heterosis magnitude indicates that the use of F1 hybrid plants improves this characteristic.
The assessment criteria for quality values are more efficient than those which merely quantify production Noda, Estudos Recentes sobre Heterose. For abbreviations see Table II.
Send correspondence to J. The F1 hybrids used were: This abstract may be abridged.
Heterosis and combining ability in eggplant. Heterosis breeding in brinjal. The hybrids displaying high heterosis also had high heterobeltiosis Table II. However, remote access to EBSCO’s databases from non-subscribing institutions is not allowed if the purpose of the use is for commercial gain through cost reduction or avoidance for a non-subscribing institution. II – Notes on the brinjal and bitter gourd.
Average early yeterosis weight.
Heterosis for different quantitative traits in brinjal (Solanum melongena L
Heterobeltiosis values were mostly negative. However, it hetetosis be useful in the Southern region when planting is carried out soon after winter. Pronounced heterosis over better-parent was observed for Plant height in Arka NidhixArka Kusmakar Pal and SinghOdland and NollIkuta and Monteiro also found significant heterosis hetsrosis for this trait.
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 plant height cm. Growing conditions were maintained similar to those normally used for brknjal commercial eggplant crop. Seeds from three of the 20 experimental hybrids obtained did not germinate. The seven cultivars, two lines, hetersis 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 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.
study of heterosis in brinjal (Solanum melongena L.) 
Users should refer to the original published version of the material for the full abstract. First class fruit yield. The high degree of heterosis heterosiw eggplants has been reported in several studies, in the Brazilian and world-wide literature Monteiro, ; Noda, ; Dixit et al.
All the other hybrids showed positive values. Cultivars Embu and B were parentals in those hybrids. 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.
Under Brazilian conditions, early yield is not a limiting trait. Studies in hybrid vigour.
