Self-pollination, intra- and interspecific crosses in tomatoes
نویسندگان
چکیده
Tomato genotypes ( Solanum spp.) have genetic variability of most desirable features, such as resistance to biotic and abiotic stresses. However, incompatibility crosses wild with domesticated tomatoes, or even between genotypes, hinders the breeding process. Thus, knowledge reproductive biology conditions is necessary maximize success artificial crossings. This study evaluated compatibility self-pollination, intra- interspecific controlled crosses, stigma receptivity, pollen viability in tomato genotypes. We used two commercial S. lycopersicum (‘RVTM08’ ‘Redenção’) seven accessions (‘AF 26970’, ‘LA-1401’, ‘AF 19684’, ‘LA-1967’, ‘PI-127826’, ‘PI-134417’, ‘LA-716’). all their reciprocals, besides self-pollinations. The variables were fruit index (FI), number seeds per (SN), seed germination percentage (GP). Stigma receptivity grains’ (PVI) also assessed. results showed that ‘LA-1967’ was self-incompatible, had a low PVI, generated without crosses. As female parents, ‘RVTM08’, ‘Redenção’, 19684’ higher FI SN. There wide diversity characteristics did not influence GP. Compatibility tomatoes determined by parent choice can be affected PVI.

Epistatic control of non-Mendelian inheritance in mouse interspecific crosses.
Strong deviation of allele frequencies from Mendelian inheritance favoring Mus spretus-derived alleles has been described previously for X-linked loci in four mouse interspecific crosses. We reanalyzed data for three of these crosses focusing on the location of the gene(s) controlling deviation on the X chromosome and the genetic basis for incomplete deviation. At least two loci control deviati...
متن کاملInteractions in Interspecific Crosses between Members of the Tomato Clade
One premise of the biological species concept (BSC) is that reproductive barriers act to prevent interbreeding between species. While the BSC is not universally applicable, interspecifi c reproductive barriers (IRBs) between species can be detected in many cases. For example, in the tomato clade ( Solanum sect. Lycopersicon ) prezygotic IRBs can prevent hybridization between certain species ( R...

اهمیت این پژوهش در آن بود که به گفت? بسیاری از پژوهشگرانِ حوز? بازبینی ترجمه، ادبیات موجود در این زمینه به لحاظ نظری و عملی چندان قوی نیست و بخش های موجود نیز برداشت مناسبی از این مرحل? فرایند ترجمه ندارند، اگرچه اخیراً توجه به آن به صورت نظام مند افزایش یافته است. در عین حال، پژوهش های موجود از یک سو بر دگربازبینی بیشتر از خودبازبینی تأکید دارند و از دیگر سو تنها به لحاظ نظری به این موضوع می پرد...
15 صفحه اولCompatibility of interspecific Manihot crosses presaged by protein electrophoresis .
Cross incompatibility of wild Manihot species with cassava (M. esculenta) can impede their utilization for improving this cultigen. We tested whether compatibility could be determined based on electrophoresis results. Manihot pilosa, M. glaziovii, M. reptans, and M. cearulescens were tested. These species were allowed to hybridize with cassava to determine whether hybridization coincides with t...
