    Abstract: A screen of rice genotypes was carried out on a total of 327 genotypes of the rice diversity panel for leaf vein density. Identifying locations of genes that impart to leaf vein density in a quantitative way should capable the using of these genes in plant breeding and accelerate producing C4 rice plant. Finding of genotypes of rice that have less ... Show More

    220, 280, 340, 400 kg k2O5/ha) occupied subplots. The statistical analysis showed superiority of irrigation at two weeks of seed cotton yield (3.75 t/h), number of open bolls per plant (20.47), number of sympodium per plant (19.65 and 17.27), ginning percentage (37.47) and water use efficiency (0.38 kg/m3). There were significant effect of potassium in traits. The level 340 kg K2O5/ha was gave the highest seed cotton yield (3.87 t/ha) due to attained the highest number of open bolls (29.25 bolls per plant for first season and gave 3.71 t/ha at 280 kg K2O5/ha due to higher boll weight (3.57 g) for second season. It could be conclude irrigation at two weeks with apply 280 kg K2O5/ha hadk attained the highest seed cotton and ginning percentage to reduce water requirements of cotton in central region of Iraq. Abstract: A field trial was conducted at Experimental Field of Field Crop Department of College of Agriculture-Abu-Graib during 2011 and 2012 seasons to investigate the effect of potassium level in growth, lint yield and its components of cotton (Gossypium hirsutum L.) cultivar Lashata was grown under abundance and deficit water conditions.

    > 8.4, SAR < 13, Ec < 4 dS/m), the cultivar of castor bean was Hindi 21. The experiments were conducted in 2010 and 2011 on the farm of Field Crops, Coll. of Agric., Univ. of Baghdad. At maturity, selected plants of those gave higher seed yield were harvested from each treatment. Selection pressure used on plant populations was 10%. In the second year, seeds from each of the three treatments with the control were planted on the same field with 53 and 89 thousand plants/ha. The design used was a factorial with RCBD of three replicates. The results revealed that selected plants from row planting out yielded the other three treatments in seed yield/plant, seed no./plant, seed weight and harvest index. The values were 61 g, 251 seeds, 0.25 g, and 9.9%, respectively. The lower planting density gave higher plant seed yield, seed no./plant and harvest index (55.6 g, 281 seeds, 8.0%). It was concluded that selection on individual plants from planting in rows was effective to create a new variation in castor bean tolerance to saline sodic soil. The higher percent of heritability was in total dry matter (98.9%), crop growth rate (98.4%), and plant seed yield (96.8%). That was indicating that genetic variance has the significant influence in phenotypic variance. Abstract: To determine the influence of selection on castor bean plants tolerance to saline sodic soil, three planting methods were used; in the bottom of furrow, at the side of furrow, and in rows of plots. The soil was saline sodic (pH > 8.4, SAR < 13, Ec < 4 dS/m), the cultivar of castor bean was Hindi 21. The experiments were conducted in 2010 a... Show More

    Abstract: Digestibility of “Tifton 85” Bermudagrass has been noted to be higher than most other Bermudagrass cultivars. However, the superior digestibility of Tifton-85 has not been verified based on samples from producers, nor is it known how water availability might affect this comparison. Recent past weather conditions in Georgia allowed this comparison. ... Show More
