Nagai and Kida  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, ) . Hence reports are available on hybrid vigor in brinjal. Pal and.

First class fruit yield. Average plant height cm. 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.
The seven cultivars, two lines, 18 F1 hybrids and two commercial hybrids heteroeis tested in a randomized complete block design with three replications at the experimental field of the ESAL campus, Lavras, MG, from February to October The eggplant Solanum melongena L.
Pronounced heterosis over better-parent was observed for Plant height in Arka NidhixArka Kusmakar The large magnitudes for this trait showed, in general, the great superiority of hteerosis F1 hybrids, compared to the open pollinated cultivars, for obtaining good quality fruit. Estudos Recentes sobre Heterose. Monteiro and Noda also reached this conclusion.
Growing conditions were maintained similar to those normally used for a commercial eggplant crop. All the other hybrids showed positive values.
Under Brazilian conditions, early yield is not a limiting trait. The values obtained hetersois 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. Heterosis breeding in brinjal. 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, users may print, download, or email articles for individual use. Expression of heterosis for productive traits in F1 eggplant Solanum melongena L.
Each experimental plot consisted of 10 plants and was spaced at 1.
study of heterosis in brinjal (Solanum melongena L.)
Send correspondence to Brihjal. Significant levels of heterosis were detected for all the traits studied. 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.
Average early fruit weight. Heterosis and combining ability in eggplant. How to cite this article. Significant heterosis relative to the parental means was detected for all traits studied.
However, it may be useful in the Southern region when planting is carried out soon after winter. 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 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 magnitude of the heterosis depended on the genotypes used.
Studies on Heterosis in Brinjal (Solanum melongena L.).
Heterobeltiosis values were mostly negative. In the temperate regions, the best prices are normally paid at the beginning of the production season, which makes early cultivars more valuable. This abstract may be abridged. Following the same tendency of the early assessment, the mean fruit weight had positive heterosis for the majority of the hybrids. The F1 hybrids used were: Cultivars Embu and B were parentals in those hybrids.
First class fruit yield is a production characteristic which allows phenotypic selection of superior genotypes, in a screening process.
