Genetic divergence in pepper genotypes from southwest Goiás Ciência e Agrotecnologia
Alvares,Renata Cristina; Reis,Edésio Fialho dos; Pinto,Jefferson Fernando Naves.
Knowledge on the genetic diversity in genebanks is important for germplasm conservation and use in breeding programs, where it can reduce time and costs of breeding of new genotypes. The purpose of this study was to evaluate the genetic divergence among 137 genotypes of Capsicum chinense Jacq. by morphological descriptors and multivariate techniques, with a view to the identification of groups for promising crosses for breeding programs. The experiment was conducted in a greenhouse, arranged in a randomized complete block design with four replications, where each plot consisted of a pot with one plant. The 20 descriptors recommended by the International Plant Genetic Resources Institute - IPGRI were considered for the morphological characterization. By...

Total of 233 rice accessions was evaluated for morphological characteristics in 2013 wet season at 5 rice research centers, namely, Pathum Thani, Chachoengsao, Phra Nakhon Si Ayutthaya, Prachin Buri and Ratchaburi. Results showed morphological variations among the accessions. In lowland rice, the accession with the earliest heading date was E-TOK KHAO (G.S. No. 5635); the latest heading date was SAMPOW TAWNG (G.S. No. 3590); the highest panicle number was LAO TAEK (PTT5602); the longest panicle was E-KHIAW NAWN TUNG (PTT5612). In floating rice, the accession with the earliest heading date was JAMPAH (G.S. No. 1689); the latest heading date was TAH PUD (G.S. No. 3751) and TAWNG MAH ENG (G.S. No. 3754); the highest panicle number was KHAO MED LEK (G.S. No....
