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.

Table I – Description of the eggplant parentals. Following the same tendency of the early assessment, the mean fruit weight had positive heterosis for the majority of the hybrids.

The hybrids displaying high heterosis also had high heterobeltiosis Table II. All the other hybrids showed positive values. Under Brazilian conditions, early yield is not a limiting trait. Data on quantitative characters were recorded and percent better-parent and standard heterosis were determined. The assessment criteria for quality values are more efficient than those which merely quantify production Noda, brimjal Average plant height cm.

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

Fourteen harvests were carried out, at seven day intervals, during a three and a half month period. For abbreviations see Table II.

Users should refer to the original published version of the material for the full abstract. 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 heteross for the majority of hybrids, with highest positive scores for hybrids Embu x Melitino, Embu x Florida Market 10 and Embu x Black Beauty. II – Notes on the brinjal and bitter gourd.

Pal and SinghOdland and NollIkuta and Monteiro also found significant heterosis results for this trait. Significant heterosis relative to the parental means was detected for all traits studied.

Services on Demand Journal. The heterosis and heterobeltiosis for hybrid early yield were also positive Table II.

However, it brknjal be useful in the Southern region when planting is carried out soon after winter. 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. 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.

The F1 hybrids used were: Heterosis breeding in brinjal. 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.

Most authors recommend the commercial heterpsis of eggplant hybrids because of heterosis for fruit yield traits Monteiro, Heterobeltiosis values were mostly negative.

Average early fruit weight. Remote access to EBSCO’s databases is permitted to patrons of heterosjs institutions accessing from remote locations for personal, non-commercial use. Cultivars Embu and B were parentals in those hybrids. However, users may print, download, or email articles for individual use.

study of heterosis in brinjal (Solanum melongena L.)

The heterosis magnitude indicates that the use of F1 hybrid plants improves this characteristic. Heterosis and combining ability in eggplant. Growing heterosix were maintained similar to those normally used for a commercial eggplant crop. Fruit characteristics are very important in eggplant breeding, as quality in vegetables is as much or more important than quantity Paterniani, On the other hand, the heterobeltiosis values were mostly negative, though the hybrid Embu x Melitino was positive and outstanding Table III.

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

When the yield characteristics are used as assessment criteria, hetfrosis is desirable that the heterosis and heterobeltiosis levels, shown in the hybrid combinations, be as high as possible.
