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.

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

Heterosis breeding in brinjal. Users should refer to the original published version of the material for the full abstract. Services on Demand Journal.

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 For abbreviations see Table II. All the other hybrids showed positive values. 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.

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

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.

Fourteen harvests were carried out, at seven day intervals, during a three and a half month period. 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. Average plant height cm. Following the same tendency of the early assessment, the mean fruit weight had positive heterosis for the majority of the hybrids.

Significant heterosis relative to the parental means was detected for all traits studied. The magnitude of the heterosis depended on the genotypes used.

Seeds from three of the 20 experimental hybrids obtained did not germinate. 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.

Each experimental plot consisted of 10 plants and was spaced at 1. Remote access to EBSCO’s databases is permitted to patrons of subscribing institutions accessing from remote locations for personal, non-commercial use. Cultivars Embu and B were parentals in those hybrids. 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.

Significant levels of heterosis were detected for all the traits studied. On the other hand, the Santa Genebra x Melitino hybrid displayed a negative heterobeltiosis value. Most authors recommend the commercial use of eggplant hybrids because of heterosis for fruit yield traits Monteiro, The assessment criteria for quality values are more efficient than those which merely quantify production Noda, 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.

However, users may print, download, or email articles for individual use. On the other hand, the heterobeltiosis values were mostly negative, though the hybrid Embu x Melitino was positive and outstanding Table III. Fruit characteristics are very important in eggplant breeding, as quality in vegetables is as much or more important than quantity Paterniani, Heterosis and combining ability in eggplant.

The F1 hybrids used were: Table I – Description of the eggplant parentals. First class fruit yield. Growing conditions were maintained similar to those normally used for a commercial eggplant crop. 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.

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. Pronounced heterosis over better-parent was observed for Plant height in Arka NidhixArka Kusmakar This abstract may be abridged. However, it may be useful in the Southern region when planting is carried out soon after winter.

A randomized complete block design with three replications was used. The fruits classified as first class corresponded to the official commercial classification, classes Extra AA and Extra A.

How to cite this article. Hybrid vigour and combining ability in eggplants. Studies in hybrid vigour. First class fruit yield is a production characteristic which allows phenotypic selection of superior genotypes, in a screening process. The hybrids displaying high heterosis also had high heterobeltiosis Table II. Send hetterosis to J. Average early fruit weight.

Monteiro and Noda also reached this conclusion.

II – Notes on the brinjal and bitter gourd. 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. The eggplant Solanum melongena L. The use of F1 hybrids in eggplants provided a quick and practical way of obtaining greater early heterrosis.
