| Abstract | ||
| A field experiments were carried out at Almushkab Rice Researchs station during 2007 to study the genetic parameters, growth, yield and its components for many rice genotypes. The design was (RCBD) in three replicates .The statistical analysis Genotypes showed highly significal difference in all characters studied. Cenotype CNT 33 gave the highest paddy yield, weight 1000 grain, and number of days from sowing to maturity at 10.09 T/h, 24.0 gm, 139 days while Genotype (T85) gave the highest number of panicles/m2 at 383.67 p/m2. While Genotype H52 gave the highest number of grain / panicle, panicle length at 187.62 grains, 24.33 cm respectively. Genetypes BT7 gave the highest plant height at 100.33 cm while Genotype VD20 gave the highest in number of day from sowing at 50% Anthesis. Number of panicle /m2, number of grain / panicle, plant height gave highest phenotypical and genotypical variability at (3127.59, 710.32, and 75.44) (1211.68, 662.77 and 64.02) respectively. Heritability in broad sense around (30.00-99.07%) for panicle length, number of days from sowing to 50% Anthesis | ||
