Floral induction by grafting without vernalization treatment (NV method) has potential to shorten breeding times and diversify the seed production of cabbage, an important leafy vegetable with a long absolute low temperature exposure requirement for its floral induction. However, it is unknown whether NV method can be actually used cabbage production. This because method’s effect on field perfo...

Fifty two genotypes of Indian bean were examined for the genetic variability parameters and trait correlation 11 yield contributing traits in F5 progenies. Analysis revealed that these had a considerable level diversity. The magnitude GCV PCV was high seed per plant, which indicated potential selection based enhancement. values moderate pod weight, pods width length. High heritability along wit...

Breeding at both interspecific and intergeneric levels is an effective method for expanding genetic variation of cruciferous crops; however, few commercially accepted varieties have been released because difficulties in generating fertile progenies. We employed backcross strategy to introduce Eruca vesicaria-specific characteristics into Brassica rapa successfully obtained four BC1F1 lines that...

Two inter-subspecific F1 hybrids have been obtained by crossing olive cultivars (‘Frantoio’ and ‘Coratina’) with pollen donors from subspecies (Olea europaea subsp. cuspidata) to enrich the germplasm of cultivated in southern China. This study aimed investigate characterization morphological traits molecular markers two their parents crosses. The showed a significant difference between genotype...

The production of green maize is considerable important for various regions Brazil. It vital that breeding programs public institutions seek to meet the needs this market sector, which has a relevant social role, mainly on small properties. aim study was estimate inbreeding depression and genetic components (m + d) characters associated with quality in three populations different basis: variety...

Background: This review aims to discuss alternatives for obtaining new clones of eucalyptus ( Eucalyptus spp.) with greater efficiency than current methods, as well the feasibility hybrid seeds. The commercial-scale use seeds may reduce implantation costs and bring other advantages forest exploitation. proposal focuses on using inbred progenies (S 1, S 2...S g) improve species. Self-fertilizati...

Shoot fly (Atherigona soccata L. Moench) is a serious pest in sorghum production. Management of shoot fly using insecticides is expensive and environmentally un-safe. Developing host-plant resistance is the best method to manage shoot fly infestation. Number of component traits contribute for imparting shoot fly resistance in sorghum and molecular markers have been reported which were closely l...

A breeding program was initiated at the Research Institute of Vegetable Crops, Skierniewice, Poland to select new tomato lines resistant to bacterial speck (Psedomonas syringae pv. tomato (PST) and suitable for field growing. Two tomato cultivars with good agronomic characteristics Luban and Rumba were crossed with resistant to PST ‘Ontario 7710’. Then backcross and pedigree breeding procedures...

N previous communications (MALOGOLOWKIN and POULSON 1957; MALOGOI LOWKIN 1958) a cytoplasmically inherited sex-ratio condition has been described in Drosophila willistoni and in D. paulistorum. In both species, certain females produce progenies consisting mostly or only of daughters. This capacity for the production of unisexual broods is inherited by their entire female progenies and is not tr...

HIS study of the primary effects of nearly continuous high-energy irradiation on mouse lifespan in the physiological ranges where reproduction is possible, has shown that the germ lines may function for as many as 24 generations at daily radiation rates of several thousand times the continuous irradiation from natural sources. The question is, at what cost? When this report was begun there were...
