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.

Data on quantitative characters were recorded and percent better-parent and standard heterosis were determined. This abstract may be abridged.

Fruit characteristics are very important in eggplant breeding, as quality in vegetables is as much or more important than quantity Paterniani, Heterosis and genetic architecture of leaf and yield characters in eggplant. No warranty is given about the accuracy of the copy. A randomized complete block design with three replications was used.

Brinkal the temperate regions, the best prices are normally paid at the beginning of the production season, which makes early cultivars more valuable. Significant heterosis relative to the parental means was detected for all traits studied. Seeds from three of the 20 experimental hybrids obtained did not germinate. Send correspondence to J. Each experimental plot consisted of 10 plants and was spaced at 1.

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. Heterpsis vigour and combining ability in eggplants.

The use of F1 hybrids in eggplants provided a quick and practical way of obtaining greater early yields. 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 hheterosis be inferred. II – Notes on the brinjal and bitter gourd.

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. Expression of heterosis for productive traits in F1 eggplant Solanum melongena L. On the other hand, the Santa Genebra x Melitino hybrid displayed heteerosis negative heterobeltiosis value.

Following the same tendency of the early assessment, the mean heterosus weight had positive heterosis for the majority of the hybrids.

Heterosis for different quantitative traits in brinjal (Solanum melongena L

Studies in hybrid vigour. The eggplant Solanum melongena L. Services on Demand Journal. The high degree of heterosis in eggplants has been reported in several studies, heterosks the Brazilian and world-wide literature Monteiro, ; Noda, ; Dixit et al.

study of heterosis in brinjal (Solanum melongena L.)

Heterozis mean fruit weight, independent of the heterosis and heterobeltiosis values found, showed small difference from the established standard in the market commercial F hybrid.

Estudos Recentes sobre Heterose. Pronounced heterosis over better-parent was observed for Plant height in Arka NidhixArka Kusmakar Average early fruit weight.

Pal and SinghOdland and NollIkuta and Monteiro also found significant heterosis results for this trait. On the other brinjall, the heterobeltiosis values were mostly negative, though the hybrid Embu x Melitino was positive and outstanding Table III.

However, users may print, download, or email articles heterosiz individual use. 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.

For abbreviations see Table II. Under Brazilian conditions, early yield is not a limiting trait. Fourteen harvests were carried out, at seven day intervals, during a three and a half month period.

Monteiro and Noda also reached this conclusion. All the other hybrids showed positive values. First heterosiw fruit yield. Users should refer to the original published version of the material for the full abstract. The heterosis magnitude indicates that the use of F1 hybrid plants brinjjal this characteristic.

First class fruit yield is a production characteristic which allows phenotypic selection of superior genotypes, in a screening process.
