Abstract:
This study is a part of rice cultivar development program in north of Iran with the aim of yield potential increase and attention to eating quality. Thirteen lines developed from the crosses between high yielding cultivars with aromatic low yield ones based on pedigree breeding method. These lines along with two controls (Neda and Sang-e-Tarom) were evaluated for agronomic and quality traits in a randomized complete block design during 2005. Farm and laboratory tests showed that lines 33-DN-1, 33-DN-18 and 32-DN-6 were superior in yield (more than 5.5 t ha(-1)) and had suitable eating quality in comparison with Sang-e-tarom as a local control.

02:27Trihybrid Crosses
Some of Mendel’s crosses examined three pairs of contrasting characteristics. Such a cross is called a trihybrid cross. A trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green).
The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an equal chance to...
