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.

Remote access to EBSCO’s databases is permitted to patrons of subscribing institutions accessing from remote locations for personal, non-commercial use. Average early fruit weight. 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.

In the temperate regions, the best prices are normally paid at the beginning of the production season, which makes early cultivars more valuable. Under Brazilian conditions, early yield is not a limiting trait.

Average plant height cm. 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. A randomized complete block design with three replications was used.

The large magnitudes for this trait showed, in general, bbrinjal great superiority of the F1 hybrids, compared to the open pollinated cultivars, for obtaining good quality fruit.

Hybrid vigour and combining ability in eggplants. Expression of heterosis for productive traits in F1 eggplant Solanum melongena L.

Heterosis and genetic architecture of leaf and yield characters in eggplant. All the contents of this journal, except where otherwise noted, is licensed under a Creative Commons Attribution License. All hybrids showed positive heterosis and heterobeltiosis for total yield Table II. Following the same tendency of the early assessment, the mean fruit weight had positive heterosis for the majority of the hybrids.

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 brinual reduction or avoidance neterosis a non-subscribing institution. Pronounced heterosis over better-parent was observed for Plant height in Arka NidhixArka Kusmakar Growing conditions were maintained similar to those normally used for a commercial eggplant crop.

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 heterosis magnitude indicates that the use of F1 hybrid plants improves this characteristic.

Pal and SinghOdland and NollIkuta and Monteiro also found significant heterosis results for this trait.

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

Heterobeltiosis values were mostly negative. However, users may print, download, or email articles for individual use.

The heterosis and heterobeltiosis for hybrid early yield were also positive Table II. Heterosis breeding in brinjal.

The magnitude of the heterosis depended on the genotypes used. Each experimental plot consisted of 10 plants and was spaced at 1. 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.

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 use of F1 hybrids in eggplants provided a quick and practical way of obtaining greater early yields.

Most authors recommend the commercial use of eggplant hybrids because of heterosis for fruit yield traits Monteiro, The eggplant Solanum melongena L.

Estudos Recentes sobre Heterose. 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.

First class fruit yield. Significant levels of heterosis were detected for all the traits studied. Significant heterosis relative to the parental means was detected for all traits studied.

On the other hand, the heterobeltiosis values were mostly negative, though the hybrid Embu x Melitino was positive and outstanding Table III. Cultivars Embu and B were parentals in those hybrids. On the other hand, the Santa Genebra x Melitino hybrid displayed a negative heterobeltiosis value.

This abstract may be abridged. For abbreviations see Table II. All the other hybrids showed positive values. When the yield characteristics are used as assessment criteria, it is desirable that the heterosis hteerosis heterobeltiosis levels, shown in the hybrid combinations, be as high as possible.

The fruits classified as first class corresponded to the official commercial classification, classes Extra AA and Extra A.
