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.

Significant levels of heterosis were detected for all the traits studied. Average plant height cm. This abstract may be abridged. Hybrid vigour and combining ability in eggplants. Pal and SinghOdland briinjal NollIkuta and Monteiro also brinjall significant heterosis results for this trait.

Heterosis for different quantitative traits in brinjal (Solanum melongena L

A randomized complete block design with three replications was used. On the other hand, the Santa Genebra x Melitino hybrid displayed a negative heterobeltiosis value. All the other hybrids showed positive values. 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.

Heterosis and combining ability in eggplant. Average early fruit weight.

Expression of heterosis for productive traits in F1 eggplant Solanum melongena L. In view of the high heterosis and or heterobeltiosis values shown for the different characteristics, the importance of the non-additive hetrosis effects in their expression can be inferred. Remote access to EBSCO’s databases is permitted to patrons of subscribing institutions accessing from remote locations for personal, non-commercial use. On the other brinjall, the heterobeltiosis values were mostly negative, though the hybrid Embu x Melitino was positive and outstanding Table III.

All hybrids showed positive heterosis and heterobeltiosis for total yield Table II. Growing conditions were maintained similar to those normally used for a commercial eggplant crop.

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

Cultivars Embu and B were parentals in those hybrids. The heterosis magnitude indicates that the use of F1 hybrid plants improves this characteristic.

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. Pronounced heterosis over better-parent was observed for Plant height in Arka NidhixArka Kusmakar Services on Demand Journal.

Most authors recommend the commercial use of eggplant hybrids because of heterosis for fruit yield traits Monteiro, The heterosis and heterobeltiosis for hybrid early yield were also positive Table II. 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 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, 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, 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. Table I – Description of the eggplant parentals. The magnitude of the heterosis depended on the genotypes used. First class fruit yield. 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.

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.

Users should refer to the original published version of the material for the full abstract. The fruits classified as first class corresponded to the official commercial classification, classes Extra AA and Extra A.

Seeds from three of the 20 experimental hybrids obtained did not germinate. The eggplant Solanum melongena L. II – Notes on the brinjal and bitter gourd. Data on quantitative characters were recorded and percent better-parent and standard heterosis were determined.

Send correspondence to J. 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.

In the temperate regions, the best prices are normally paid at the beginning of the production season, which makes early cultivars more valuable. Following the same tendency of the early assessment, the mean fruit weight had positive heterosis for the majority of the hybrids. Heterobeltiosis values were mostly negative.
