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.

Heterosis breeding in brinjal. The magnitude of the heterosis depended on the genotypes used. Studies in hybrid vigour. 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.

In the temperate regions, the best prices are normally paid at the beginning of the production season, which makes early cultivars more valuable. Heterosis and genetic architecture of heterisis and yield characters in eggplant.

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

Average plant height cm. Seeds from three of the 20 experimental hybrids obtained did not germinate. The use of F1 hybrids in eggplants provided a quick and practical way of obtaining greater early yields. The assessment criteria for quality values are more efficient than those which merely quantify production Noda, The fruits classified as first class corresponded to the official commercial classification, classes Extra AA and Hterosis A.

Growing conditions were maintained similar to those normally used for a commercial eggplant crop. Pronounced heterosis over better-parent was observed for Plant height in Arka NidhixArka Kusmakar The eggplant Solanum melongena L. However, it may be useful in the Southern region when planting is carried out soon after winter.

Fourteen harvests were carried out, at seven day intervals, during a three and a half month period. Significant heterosis relative to the parental means was detected for all traits studied. The high degree of heterosis in eggplants has been reported in several studies, in the Brazilian and world-wide brknjal Monteiro, ; Noda, ; Dixit et al.

Data on quantitative characters were recorded and percent better-parent and standard heterosis were determined. 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 On the other hand, the heterobeltiosis values were mostly negative, though the hybrid Embu x Melitino was positive and outstanding Table III.

How to cite this article. A randomized complete block design with three replications was used. 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. On the other hand, the Santa Genebra x Melitino hybrid displayed a negative heterobeltiosis value. brinual

Under Brazilian conditions, early yield is not a limiting trait. However, users may print, download, or email articles for individual use. First class fruit yield. II – Notes on the brinjal and bitter gourd.

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.

All hybrids showed positive heterosis and heterobeltiosis for total yield Table II. Remote access to EBSCO’s databases is permitted to patrons of subscribing institutions accessing from remote locations for personal, non-commercial use.

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.

No warranty is given about the accuracy of the copy. 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 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.

The F1 hybrids used were:
