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.

Expression of heterosis for productive traits in F1 eggplant (Solanum melongena L.) hybrids

Monteiro and Noda also reached this conclusion. The large magnitudes for this trait showed, in general, the great superiority of the F1 heteeosis, compared to the open pollinated cultivars, for brijjal good quality fruit. 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. The heterosis magnitude indicates that the use of F1 hybrid plants improves this characteristic.

A randomized complete block design with three replications was used. All the other hybrids showed positive values.

Under Brazilian conditions, early yield is not a limiting trait. The magnitude of the heterosis depended on the genotypes used.

Users should refer to the original published version of the material for the full abstract. First class fruit yield is a production characteristic which allows phenotypic selection of superior genotypes, in a screening process. Following the same tendency of the early assessment, the mean fruit weight had positive heterosis for the majority of the hybrids.

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.


Pronounced heterosis over better-parent was brinjzl for Plant height in Arka NidhixArka Kusmakar Each experimental plot consisted of 10 plants and was spaced at 1.

On the other hand, the Santa Genebra x Melitino hybrid displayed a negative heterobeltiosis value. II – Notes on the brinjal and bitter gourd. All the contents of this journal, except where otherwise noted, is licensed under a Creative Commons Attribution License. Services on Demand Journal.

The fruits classified as first class corresponded to heteroeis official commercial classification, classes Extra AA and Extra A. Heterosis and combining ability in eggplant. Studies in hybrid vigour. For abbreviations see Table II.

Estudos Recentes sobre Heterose. 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. The F1 hybrids used were: 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.

However, it may be useful in the Southern region when planting is carried out soon after winter. Significant heterosis relative to the parental means was detected for all traits studied.

The heterosis and heterobeltiosis for hybrid early yield were also positive 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.

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 Remote access to EBSCO’s databases is permitted to patrons of subscribing institutions accessing from remote locations for personal, non-commercial use. 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.


Heterosis breeding in brinjal.

Send correspondence to J. Most authors recommend the commercial use of eggplant hybrids because of heterosis for fruit yield traits Monteiro, 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 jeterosis tomato cultivars and hybrids having high quality and yield attributes.

Heterosis and genetic architecture of leaf and yield characters in eggplant. Fourteen harvests were carried out, at seven day intervals, during a three and a heterosls month period.

Heterosi levels of heterosis were detected for all the traits studied. On the other hand, the heterobeltiosis values were mostly negative, though the hybrid Embu x Melitino was positive and outstanding Table III. 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.
