generation mean analysis was carried out to estimate the nature andmagnitude of gene effects for sugar yield and its component traits in sweet sorghum[sorghum bicolor (l.) moench. six basic generations, namely p1, p2, f1, f2,bc1p1, bc1p2 of four crosses involving seven diverse parents were evaluated inrainy 2009. the mean performance of the f1 in all the crosses indicated dominantgene effect fo...

melon is an economically important crop and iran is considered as its diversity center. to investigate gene action, heritability and number of effective factors for yield and related traits, six generations, namely: p1, p2, f1, f2, bc1, and bc2 of two crosses of mirpanji × tashkandi and mirpanji × abasali were produced and evaluated in the spring of 2008, applyig a complete block design of thre...

satureja rechingeri, belonging to the family lamiaceae, has been recently used in the pharmaceutical industry due to its high level of carvacrol in the essential oil. the domestication and breeding of suitable s. rechingeri variety has been started since few years ago in iran. the initial screening of natural populations, grown in the same environment, was performed and 58 talent clones were se...

Analysis of generation mean was carried out in six crosses of rice viz., ADT 41 / ADT 46, ADT 41 / CO 47, ADT 41 /TKM 9, ADT 41/ Jeeragasamba, ADT 41/ACM 98003 and ADT 41/AS 90033 for hulling percentage, milling percentage, head rice recovery, kernel length, kernel breadth, kernel L/B ratio, kernel length after cooking, linear elongation ratio and alkali spreading value. The scaling test showed...

In the present investigation, γ-alumina nanoparticles with particle sizes less than 10 nm, high specific surface area (351 m2/g), high pore volumes and relatively narrow pore sizes distribution was prepared via sol-gel method in presence of aluminum isopropoxide as an aluminum precursor, distilled water, acetic acid as hydrolysis rate controller and tert-butanol as solvent. They had meso ...

A model of unlinked diallelic loci affecting the risk of a complex inherited disease is explored. The loci are equivalent in their effect on disease risk and are in Hardy-Weinberg and linkage equilibrium. The goal is to determine what assumptions about dependence of disease risk on genotype are consistent with data for diseases such as schizophrenia, bipolar disorder, autism, and multiple scler...

This research was undertaken to assess genetic control and combining effects of some essential traits yield under drought stress. Forty-two hybrids water-stressed well-watered conditions were tested in field experiments for two years. Evaluation the various components variation performed. Both additive (D) dominant (H1) variance important most suggesting both non-additive gene conditions. The s...
