Brassica carinata (BBCC), a potential oilseed crop for dry land agriculture, is sensitive to high temperatures during germination and early stages of growth, which thereby restricts the possibility of using the residual soil moisture available after the rainy season for its cultivation. To overcome this problem, a three‐genome hybrid, RCBB, was synthesized using Raphanus sativus (RR) and Brassica oleracea (CC) as donor sources for the desired heat tolerance. Protoplasts of RC hybrids obtained through sexual crosses between R. sativus (female) and B. oleracea (male) were fused with protoplasts of Brassica nigra (BB) to produce RCBB somatic hybrids. The hybrid colonies regenerated with an average frequency of 7.6%. Twelve out of 36 hybrids grown to maturity were characterized for their nuclear and organelle genomes. While all the hybrids showed the presence of B. nigra chloroplasts, 10 of the hybrids showed B. nigra‐specific mitochondria and two had Raphanus‐spedfic mitochondria. The somatic hybrids could be backcrossed to B. carinata. 相似文献

锌、锰对棉花吸收氮、磷养分的影响及机理研究 总被引：5，自引：0，他引：5
较高或较低浓度的土壤锌、锰影响棉花对氮、磷养分的吸收、而合适的土壤锌、锰浓度能促进棉花根系和地上部对氮、磷的吸收和积累。提高植株及茎、叶、蕾、铃中氮、磷的含量,对棉花的生产发育,产量及产量构成因素都表现出明显的促进作用,通过水培试验研究发明,锌、锰在一定浓度条件下所表现的促进作用,主要是提高了棉花植株的根系活力,增加棉株叶片的叶绿素含量,调节棉株体内的酶活性,从而增加了棉花对营养物质的吸收、运输和代谢、提高了氮、磷的利用率、增加棉花的产量。 相似文献

Hybrids of Bread Wheat (Triticum aestivum) with Thinopyrum scirpeum (4x) and Thinopyrum junceum (6x)
Hybrids were obtained by crossing Thinopyrum scirpeum (4x) and T. junceum (6x) onto Triticum aestivum cv, ‘Chinese Spring’. An average meiotic pairing of 24.44I+ 5.07II+ 0.14IIIin the ‘Chinese Spring’×T. scirpeum hybrid (ABDE1E2) is attributed to two similar genomes from T. scirpeum (E1E2E3E4). An average meiotic chromosome pairing in the other hybrid (ABDJ1J2E3) was 31.70I+ 3.80II+ 0.90III and is attributed to autosyndetic pairing between the three genomes of T. junceum. 相似文献

The successful interspecific cross is reported for the first time between kenaf (Hibiscus cannabinus L.), a diploid species (2n=36) and roselle (Hibiscus sabdariffa L.), a tetraploid species (2n=72). Kenaf, grown for its bast fiber and also under investigation as a source of paper pulp, is fast-growing and well adapted to mechanical harvesting, but susceptible to root-knot nematodes. Roselle, also grown for its bast fiber, is slower growing, not well adapted to mechanical harvesting, but certain varieties are resistant to root-knot nematodes. Five hybrid plants were produced from the pollination of 4,445 flowers of kenaf with pollen from roselle; no hybrid plants were produced from 2,655 pollinations made in the reciprocal direction. One line of roselle was the parent of 3 of the 5 hybrids; one line of kenaf was the parent of 2 of these 3. The F1 hybrids were triploid, and varied in vigor, growth habit and vegetative morphology, but had similar flowers. Two of the F1 hybrids showed high pollen fertility, apparently as a result of restitution at first meiotic division leading to unreduced spores. These two hybrids each produced a small amount of seed, which gave rise to an F2 population of 22 plants. The F2 plants vary in vigor but are morphologically uniform, have thick leaves with mosaic sectors, and are presumably spontaneous allohexaploids. The theoretical possibilities of increasing the percentage of recovery of the F1 interspecific hybrids and of developing a synthesized hybrid variety useful for bast fiber and paper pulp are discussed. 相似文献

Summary To introduce resistance to fungal and viral diseases into urdbean (Vigna mungo), it was crossed with adzukibean (Vigna angularis) to achieve an interspecific hybrid between the two species by using different non-conventional breeding methods. Partial success was obtained with the use of UV irradiated pollen, intraspecific hybrids as parents and spray of immuno-suppressants on the female parent under glass house conditions and to the extent of callusing in aseptic culture. 相似文献

Summary Discriminating styles (DS) in Petunia hybrida discriminate among incompatible pollen sources with pollen-mediated pseudo-self compatibility (PMPSC) similarly to those in Nemesia strumosa. Both species exhibit a single-locus gametophytic self-incompatibility system. Correlation of PMPSC to PSC level of the male was not universal and DS/PMPSC operated in heterozygous S genotypes. PSC levels of progenies generated from compatible or incompatible bud pollination were not significantly different from those of open-flower pollination of a DS plant with a given male, suggesting that DS did not select among male gametophytes for increased PSC.Scientific Journal Series Paper Number 13,077 of the Minnesota Agricultural Experiment Station. 相似文献
