Identification of molecular marker linked to resistance gene loci against Indian isolate of Phytophthora capsici L. causing root rot in chilli (Capsicum annuum L.)

Phosphite has been recommended to enhance plant resistance against Phytophthora. This work evaluated the response of hot and sweet pepper (Capsicum annuum L.) to Phytophthora capsici from juvenile up to the adult stage following treatment with phosphite. Sweet pepper hybrids considered to be resistant to P. capsici, like Reinger, Nathalie and Athenas, were evaluated. The susceptible checks were hybrid Magali R and cvs. Myr 10 and Ikeda. Hot pepper Criollo de Morelos 328, CM 334, BGH 3756, BGH 5122, CNPH 294 and Locorte were used as referential resistant lines. Phosphite did not have an effect on the hot pepper resistant lines because of their genetic homozygozity, while no protection was observed for the Athenas hybrid claimed to be resistant. Heterozygous hybrids recognized as resistant, like Reinger and Nathalie, showed higher survival following phosphite treatment, and their reaction was equivalent to the resistant cvs. CM 328 and CM 334, except for the fruiting stage. Depending of the hybrid heterozygous genotype, phosphite possibly acts through indirect phytoalexin induction through the inhibited pathogen.

Perlakuan benih menggunakan rizobakteri sebagai alternatif pengganti penggunaan bahan kimia untuk mengendalikan penyakit tanaman. Penelitian ini bertujuan (1) menyeleksi keefektifan isolat rizobakteri dalam menghambat pertumbuhan Phytophthora capsici secara in vitro, dan (2) mempelajari pengaruh perlakuan benih menggunakan rizobakteri terhadap pertumbuhan P. capsici, vigor benih dan pertumbuhan tanaman. Penelitian ini terdiri atas dua tahap percobaan, kedua percobaan tersebut menggunakan rancangan acak lengkap. Percobaan satu (pesemaian) terdiri atas lima taraf yaitu perlakuan benih dengan rizobakteri ST116B, ST156, E3, metalaksil, dan tanpa perlakuan (kontrol). Percobaan dua (di rumah kaca) terdiri atas enam taraf yaitu perlakuan rizobakteri ST116B, ST156, E3, metalaksil, kontrol positif, dan kontrol negatif. Terdapat 7 rizobakteri dari 23 isolat yang diuji yaitu ST156, E3, ST116B, ST81, SK7, ST116, dan ST109B menghambat pertumbuhan P. capsici secara in vitro. Perlakuan benih dengan rizobakteri ST116B, ST156, dan E3 nyata meningkatkan vigor benih pada tolok ukur indeks vigor. Perlakuan benih terbaik dalam meningkatkan pertumbuhan tanaman (jumlah daun) dan berpotensi mengendalikan penyakit busuk phytophthora pada tanaman cabai adalah dengan rizobakteri ST116B.
