Mapping Panel

Pepper (Capsicum annuum L.) is an economically significant global crop and condiment. Its yield can be severely reduced by the oomycete plant pathogen, Phytophthora capsici (P. capsici). Here, a high-density genetic map was created with a mapping panel of F2 populations obtained from 150 individuals of parental lines PI201234 and 1287 and specific-locus amplified fragment sequencing (SLAF) that was then utilized to identify loci that are related to resistance to P. capsici. The sequencing depth of the genetic map was 108.74-fold for the male parent, 126.25-fold for the female parent, and 22.73-fold for the offspring. A high-resolution genetic map consisting of 5565 markers and 12 linkage groups was generated for pepper, covering 1535.69 cM and an average marker distance of 0.28 cM. One major quantitative trait locus (QTL) for the P. capsici resistance (CQPc5.1) was identified on Chr05 that explained the observed 11.758% phenotypic variance. A total of 23 candidate genes located within the QTL CQPc5.1 interval were identified, which included the candidate gene Capana05g000595 that encodes the RPP8-like protein as well as two candidate genes Capana05g000596 and Capana05g000597 that encodes a RPP13-like protein. Quantitative reverse-transcription PCR (qRT-PCR) revealed higher expression levels of Capana05g000595, Capana05g000596, and Capana05g000597 in P. capsici resistance accessions, suggesting their association with P. capsici resistance in pepper.

Capsicum Annuum L

With protected agriculture, plants are sheltered from adverse climatic conditions, and the solar radiation that impacts the plants is modif ied with the purpose of improving their productivity. Therefore, the objective of our study was to evaluate the effect of the material and color of four greenhouse covers over the rate and spectral characteristics of the transmitted radiation, and their relation with chlorophyll content, growth and yield of poblano pepper (Capsicum annuum L.) cv Ébano culture. The study was conducted in four oval shaped macro-tunnels (4 m wide, 2.5 m high and 12 m long). The covers of three macro-tunnels consisted of red, blue and translucent polycarbonate sheets, respectively, and the remaining macro-tunnel cover was high-density diffuse polyethylene. Spectral characteristics of the solar radiation transmitted in each cover were determined using a spectroradiometer. The photosynthetically active radiation (PAR) rate within and outside each macro-tunnel was obtained using quantum sensors. The results of our study showed that plants that grew under polycarbonate covers of different colors presented more chlorophyll content than plants under the high-density polyethylene cover and those from open f ield. Due to the lower rate of PAR and almost null radiation transmissivity from 400 to 570 nm, plants that grew under red polycarbonate sheets were taller and with more foliage, but with lower fruit yield. The highest fruit yield was observed under the translucent polycarbonate and high-density polyethylene covers.

<em>Konsumsi cabai rawit terus meningkat namun produktivitasnya masih rendah, sehingga diperlukan pemuliaan yang mengarah pada perbaikan daya hasil. Penelitian ini bertujuan untuk menganalisis keragaman genetik, korelasi antar karakter, heritabilitas arti luas, dan nilai kemajuan seleksi populasi F3 cabai rawit. Penelitian ini dilaksanakan di Kebun Percobaan Leuwikopo, IPB, Dramaga, Bogor dan Laboratorium Genetika dan Pemuliaan Tanaman, Departemen Agronomi dan Hortikultura, IPB. Percobaan menggunakan 5 genotipe tetua dan 6 genotipe F3 cabai rawit, dengan genotipe tetua yang diulang sebanyak 3 ulangan dan genotipe F3 tanpa ulangan. Hasil penelitian menunjukkan bahwa karakter bobot buah per tanaman dan jumlah buah per tanaman memiliki keragaman genetik luas pada semua genotipe. Semua karakter pengamatan berkorelasi positif terhadap daya hasil kecuali umur berbunga dan umur panen. Nilai heritabilitas arti luas dengan kriteria tinggi terdapat pada karakter bobot buah per tanaman, bobot per buah, dan panjang buah. Hasil seleksi indeks yang dilakukan menunjukkan kemajuan seleksi yang besar pada karakter bobot buah per tanaman dan jumlah buah per tanaman.</em>
