HETEROSIS BRINJAL PDF

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.

Send correspondence to J. Pronounced heterosis over better-parent was observed for Plant height in Arka NidhixArka Kusmakar Significant heterosis relative to the parental means was detected for all traits studied.

On the other hand, the Santa Genebra x Melitino hybrid displayed a negative heterobeltiosis value. First class fruit yield.

The F1 hybrids used were: II – Notes on the brinjal and bitter gourd. The eggplant Solanum melongena L.

Estudos Recentes sobre Heterose. The use of F1 hybrids in eggplants provided a quick and practical way of obtaining greater early yields. This brinjxl may be abridged. The heterosis and heterobeltiosis for hybrid early yield were also positive Table II. Heterobeltiosis values were mostly negative. 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.

Most authors recommend the commercial use of eggplant hybrids because of heterosis for fruit yield traits Monteiro, Each experimental plot consisted of 10 plants and was spaced at 1. Under Brazilian conditions, early yield is not a limiting trait. 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 brinajl and Embu x Black Beauty.

No warranty is given about the accuracy of brinja copy. First class fruit yield is a production characteristic which allows phenotypic selection of superior genotypes, in a screening process.

The large magnitudes for this trait showed, in general, the great superiority of the F1 hterosis, compared to the open pollinated cultivars, for obtaining brimjal quality fruit.

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

Users should refer to the original published version of the material for the full abstract. Heterosis and genetic architecture of leaf and yield characters in eggplant. bribjal

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 heteorsis as possible. However, users may print, download, or email articles for individual use. 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. Average plant height cm.

study of heterosis in brinjal (Solanum melongena L.) [1979]

The hybrids displaying high heterosis also had high heterobeltiosis Table II. 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. All the other hybrids showed positive values.

All hybrids showed positive heterosis and heterobeltiosis for total yield Table II. In the temperate regions, the best prices are normally paid at the beginning of the production season, which makes early cultivars more valuable. 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. 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.

Fruit characteristics are very important in eggplant breeding, as quality in vegetables is as much or more important than quantity Paterniani, Studies in hybrid vigour. 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 Heterosis breeding in brinjal.

Seeds from three of the 20 experimental hybrids obtained did not germinate. Pal and SinghOdland and NollIkuta and Monteiro also found significant heterosis results for this trait.

Average early fruit weight. All the contents of this journal, except where otherwise noted, is licensed under a Creative Commons Attribution License. Expression of heterosis for productive traits in F1 eggplant Solanum melongena L.

Monteiro and Noda also reached this conclusion. For abbreviations see 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. 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.

Heterosis and combining ability in eggplant. How to cite this article. Services on Demand Journal. Growing conditions were maintained similar to those normally used for a commercial eggplant crop. Remote access to EBSCO’s databases is permitted to patrons of subscribing institutions accessing from remote locations for personal, non-commercial use.

Following the same tendency of the early assessment, the mean fruit weight had positive heterosis for the majority of the hybrids. Data on quantitative characters were recorded and percent better-parent and standard heterosis were determined.

Hybrid vigour and combining ability in eggplants. However, it may be useful in the Southern region when planting is carried out soon after winter.
