Heterosis breeding is used to improve yield quantity and quality of Tomato ( Solanum Exploitation of hybrid vigor in Tomato (Solanum lycopersicum L.) is economical and easy International Journal of Vegetable Science. study. Yield and leaf area showed highly significant heterosis in F1 hybrids ranging from to % and .. Harayana Agricultural University Journal of. Seven F1 wheat hybrids were tested at two different spacings of the plants within the rows. Although some crosses exhibited heterosis none yielded significantly.

Positive heterosis for plant height range from 1. Journal of Agricultural Science, 4 11 Moreover, expressive differences among genotypes were found and values varied jutnal 21 to 31 days.

Karnataka Journal of Agricultural Science, 21 4— Latvian Journal of Agronomy, 45 17— Parent F KG6 had the highest fruit number per plant. Estimates of general and specific combining ability GCA and SCAand mean square effects for eight agronomic traits in diallel crosses from six chili peppers parents, according to Method 2, Model 1 Griffing, Email the author Login required.

Heterosis and combining ability for ornamental chili pepper

However, for ornamental purposes, small-sized plants are preferred for pot cultivation. Seedlings were produced in polystyrene trays with cells containing commercial subtract and transplanting was conducted when the seedlings had four to six pairs of definitive leaves, by transferring them into 5-liter plastic pots filled spacing 1. Estimation of heterosis and combining ability in maize Zea mays L. It must be highlighted that small-sized fruits and in higher number are ideal for ornamental chili pepper production.

Chili peppers Capsicum annuum for ornamental purpose has gained scope representing new options such as cultivation of potted plants in gardens and also as cut foliage. Retrieved from website Farid, M. Capsicum annuum; ornamental breeding; ideotype; diallel analysis.

Jurnal Hortikultura, 22 2— Study of heterosis in Bangladesh Chili Capsicum annuum L. A generalised treatment of the use of diallel crosses in quantitative inheritance. Breeding programs can use heterosis and combining ability information, aiming to commercially explore hybrids or develop heteross for lineage selection with desirable characteristics.

The ornamental plant sector requires cultivars adapted to different cultivation conditions in pots and gardens. There was a highly significant difference for all characteristics in terms of GCA and SCA, indicating that additive and dominance effects are important to control the studied traits. Estimation of heterosis for yield and quality components in chilli Capsicum annuum L.

The averages for HET1 varied from 6. Days to fruiting varied from 44 to 52 days after transplanting, enabling a selection of early genotypes. Regarding canopy diameter, there was no significant difference among treatments and values varied from In general, these results indicated predominance of GCA effects in relation to SCA ones, which means predominance of additive effects on height characteristic before and afterwards fruiting ; days to ehterosis fruit length and diameter, and number of fruits per plant.

Study on combining ability and heterosis of yield and its components in pepper Capsicum annum L. In sequence, fruit length and number of fruits per plant had also great amplitude of variation in averages, both composing six classes. Heterosis calculation was carried out based on the average of parents according to formula: Retrieved from website Khalil, M.

These investigations lead to the conclusion that data obtained in this study are in the limits of heterosis observed for studies with Capsicum. African Journal of Biotechnology, 12 47 heterowis, — Alexandria Journal of Agricultural Research, 59 161— Both additive and dominance effects play important role in controlling the studied characters, indicating hybrid exploitation as well as development of superior lineages from the progress of segregating generations.

Agronomika, 10 11— Brazilian ornamental pepper breeding program: Aiming to develop new cultivars for ornamental chili pepper market, and considering a chili pepper ideotype proposed, which consists in small-sized plants up to 30 cmprecocious in days to flourishing and fruiting, and in high number of fruits per plant, the following hetsrosis could be recommended: Cardosowhen studying pollination with zucchini, suggested that the increment jurnwl number of seeds per plant is explained by the use of high quantity of pollen.

Heterosis studies in chilli Capsicum annuum L. The coefficient of variation CV jurnla were between proposed limits for Capsicum genus according to Silva et al. Morpho-agronomic characterization juranl accomplished considering different parts of plants, according to Capsicum genus descriptors proposed by IPGRI and some modifications proposed by Silva et al. Hybrid combinations, number of crosses performed, number of fruits, crossing success rate and number of seeds produced in crosses between six parents of Capsicum annuum.

Regarding the character HET1, 11 hybrid combinations had satisfactory results, with negative values for the following characters: Jurnal Agronomi Indonesia, 39 2— Combining ability for earliness and productivity in sweet pepper Capsicum annuum L.

Six accessions of Capsicum annuum from germplasm bank of the Universidade Estadual do Norte Fluminense Darcy Ribeiro UENF Table 1 were selected based on preliminary studies for indication of genitors with potential ornamental use Silva et al.

Such reductions are desirable for ornamental Capsicum breeding programs. The following fruit characteristics were evaluated: Combining ability of several introduced and local chilli pepper Capsicum annuum L. Diallel analysis of chili Capsicum annuum L. To the expansion and valorization of this market segment, new products are required to supply the demand and attract potential supporters of the ornamental plant consumption.
