Bio-priming of Aceh local chili seeds in the effort to increase production and begomo virus resistance

Abstract

The purpose of this study was to determine whether P60 could induce resistance in local Aceh chili varieties to begomovirus and compared with national varieties. This research was conducted at the Experimental Farm, Genetics and Plant Breeding Laboratory, Faculty of Agriculture, Syiah Kuala University, Banda Aceh, from March to July 2021. This study used a factorial randomized block design. The tested factors consisted of two factors. The first factor is bio priming. The second factor consists of four local Aceh chili varieties, namely: V1 = Odeng, V2 = Lanyoe, V3 = Super Lamando and V4 = LamandoLapaben and one national variety, namely V5 = Baja F1 as a comparison variety. The results showed that the best local Aceh variety was LamandoLapaben for the variables of resistance response, incubation period, disease intensity, disease incidence, stem diameter, and crown width. The best local variety Aceh Lanyoe on plant height and dichotomous height parameters. Giving P60 can reduce the percentage of disease incidence by 52.00% and slow down the process of emergence of disease symptoms (incubation period) 27.11 DAP. The best combination treatment was the LamandoLapaben variety, which was 1.41 milligram Units-1 (Umg)-1.

Application of Rhizobacteria to Control Phytophthora capsici Disease Causes Stem Base Rot and Increase Growth of Pepper Seedlings In-Vivo

“…Seed bio-priming treatment increases the resistance of local cayenne pepper plants [23]. Bio-priming seeds with biological agents can also increase plant resistance to pathogens [243].…”

Biopriming benih dalam meningkatkan pertumbuhan dan hasil tanaman kacang tanah (Arachis hypogeae L.)

“…Lebih lanjut dilaporkan bahwa, kombinasi agens hayati mampu juga mampu meningkatkan kosentrasi IAA pada akar tanaman tembakau (Begum et al, 2022). Hapsah et al (2022) melaporkan bahwa perlakuan biopriming benih mampu meningkatkan respon resistensi ketahanan tanaman dan pertumbuhan bibit tanaman cabai rawit lokal. Biopriming benih dengan menggunakan agens hayati mampu memacu pertumbuhan kecambah benih dan meningkatkan ketahanan tanaman terhadap terhadap penyakit tanaman (Chin et al, 2022).…”

The potential and the quality of several open pollinated chili varieties seed production

“…[22,23], Ancho and Guajillo chili (Capsicum annuum L.) [24][25][26], Capsicum frutescens L. [27,28], Capsicum baccatum [29] have been reported. Likewise, reports related to seed productions of local chili varieties (Odeng, Lanyoe, Super Amando, and Lamando Lapaben from Aceh [30]; Katokkon chili from Sulawesi [23]; Pulau Timor [31]) or nasional varieties (IPB CH1, IPB CH2, IPB CH3, IPB CH4, IPB CH5, IPB CH6, IPB CH25, IPB CH28, and IPB CH50 varieties owned by IPB University [32]; UNIB C H73, UNIB C H65, and UNIB C H13 varieties owned by Universitas Bengkulu [33]; CK5 variety owned by Universitas Padjadjaran [31]; PM999, Kiyo [34], or Arimbi [35] varieties owned by private companies have also been reported. Information related to the potential and quality of seeds owned by the Ministry of Agriculture already exists but there are still few who report as a whole related to the potential productions and seed qualities [36][37][38][39][40].…”
