Genetics Diversity and Agronomic Characters of F3 Lines Selected by Recurrent Selection for Drought Tolerance and Blast Resistance of Bengkulu Local Rice Varieties

“…The adjusted average value = Yi -Pj (2) where: Pj = effect blocks all j Bj = average control in one block j M = average common control Yi = the value of the i-th observation genotype Plots measuring 6 m x 5 m consists of 12 F1 lines. Each line planted two rows of each row contained 12 holes planting and planted two seeds per hole.…”

“…Local varieties had been planted by farmers for many generations on the specific agroecological region so that presumably they are resistant/tolerant to biotic or abiotic stresses in a specific location. Use of local varieties as parental hybridization is recommended for getting superior specific genotype on the new varieties so that released varieties should have a broad genetic variability [1], [2], [3]. Specific local rice breeding in conventional methods in a dry land to improved high yielding couldn't do without known genetic problems and the way of heritability desiring.…”
