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.

Pal and SinghOdland and NollIkuta and Monteiro also found significant heterosis results for this trait.

Average early fruit weight. Send correspondence to J. This abstract may be abridged. Seeds from three of the 20 experimental hybrids obtained did not germinate. Each experimental plot consisted of 10 plants and was spaced at 1.

The magnitude of the heterosis depended on the genotypes used. Significant levels of heterosis were detected for all the traits studied. In the temperate regions, the best prices are normally paid at the beginning of the production season, which makes early cultivars more valuable. Users should refer to the original published version of the material for the full abstract.

Heterosis and combining ability in eggplant.

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

Growing conditions were maintained similar to those normally used for a commercial eggplant hetsrosis. The F1 hybrids used were: Monteiro and Noda also reached this conclusion. The large magnitudes for this trait showed, in general, the great superiority of the F1 hybrids, compared to the open pollinated cultivars, for obtaining good quality fruit.

The high degree of heterosis in eggplants has been reported in several studies, in the Brazilian and world-wide literature Monteiro, ; Noda, ; Dixit et al. First class fruit yield. Average plant height cm. The 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. A randomized complete block design with three replications was used.

Following the same tendency of the early assessment, the mean fruit weight had positive heterosis for heterosiis majority of the hybrids. Pronounced heterosis over better-parent was observed for Plant height in Arka Hetersis Kusmakar 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.

On the other hand, the Santa Genebra x Melitino hybrid displayed a negative heterobeltiosis value. 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. The use of F1 hybrids in eggplants provided a quick and practical way of obtaining greater early yields.

Heterosis for different quantitative traits in brinjal (Solanum melongena L

The eggplant Solanum melongena L. II – Notes on the brinjal and bitter gourd. How to cite this article. Most authors recommend the commercial use of eggplant hybrids because of heterosis for fruit yield traits Monteiro, Remote access to EBSCO’s databases is permitted to patrons of subscribing institutions accessing from remote locations for personal, non-commercial use.

However, remote access to EBSCO’s databases from non-subscribing institutions is not allowed if the purpose of the use is heterosus commercial gain through cost reduction or avoidance for a non-subscribing institution.

bronjal 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 development of improved tomato cultivars and hybrids having high quality and yield attributes. Under Brazilian conditions, early yield is not a limiting trait. The assessment criteria for quality values are more efficient than those which merely quantify production Noda, No warranty is given about the accuracy of the copy.

Services on Demand Journal. All hybrids showed positive heterosis and heterobeltiosis for total yield Table II. Heterobeltiosis values were mostly negative. All the contents of this journal, heterosiis where otherwise noted, is licensed under a Creative Commons Attribution License.
