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.

Average early fruit weight. Data on quantitative characters were recorded and percent better-parent and standard heterosis were determined.

Average plant height cm. The use of F1 hybrids in eggplants provided a quick and practical way of obtaining greater early yields. 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.

Under Brazilian conditions, early yield is not a limiting trait. The eggplant Solanum melongena L.

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

All hybrids showed positive heterosis and heterobeltiosis for total yield Table II. Monteiro and Noda also reached this conclusion. The heterosis and heterobeltiosis for hybrid early yield were also positive Table II. Pal and SinghOdland and NollIkuta and Monteiro also found significant heterosis results for this trait.

On the other hand, the heterobeltiosis values were mostly negative, though the hybrid Embu x Melitino was positive and outstanding Table III. Remote access to EBSCO’s databases is permitted to patrons of brnijal institutions accessing from remote brinjap 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.

Heterosis and genetic architecture of leaf and yield characters in eggplant. The heterosis magnitude indicates that the use of F1 hybrid plants improves this characteristic.

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

How to cite this article. 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.

Studies in hybrid vigour. Seeds from three of the 20 experimental hybrids obtained did not germinate. For abbreviations see Table II. First class fruit yield. The mean fruit weight, independent of the heterosis and heterobeltiosis values found, showed small difference from the brinmal standard in the market commercial F hybrid. The fruits classified as first class hegerosis to the official commercial classification, classes Extra AA and Extra A.

Heterosis breeding in brinjal. Each experimental plot consisted of 10 plants and was spaced at 1. 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.

Studies on Heterosis in Brinjal (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. 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.

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. Heterosis and combining ability in eggplant. 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.

Significant heterosis relative to the parental means was detected for all traits studied. Most authors recommend the commercial use of eggplant hybrids because of heterosis for fruit yield traits Monteiro, All the contents of this journal, except where otherwise noted, is licensed under a Creative Commons Attribution License. A randomized complete block design with three replications was used.

Cultivars Embu and B were parentals in those hybrids. The magnitude of the heterosis depended on the genotypes used. The hybrids displaying high heterosis also had high heterobeltiosis Table II. Users should refer to the original published version of the material for the full abstract.

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. Estudos Recentes sobre Heterose.
