to assess heritability, gene action and combining ability of rice varieties for characteristics related to grain appearance and cooking quality, the progenies derived from direct and reverse crosses of the 6×6 complete diallel together with their parents included hashemi, hassani, shahpasand, kadous, vandana and ir36 were grown in a randomized complete block design with three replications in th...
In order to analyze the genetics of tobacco cultivars’ resistance to blue mould (Peronospora tabacina A.) and to estimate the combining ability of the four resistant and susceptible tobacco cultivars (Bel 61-10, Bergerac C, Samsoun and Trumpf) received from CORESTA, these cultivars were crossed in 1997 in a half-diallel crossing system and in 1998 their parents and their progenies were sowed. A...
In order to investigate the inheritance pattern of indeterminate growth in Vigna radiata, various related traits were studied. The techniques used for the purpose were generation mean and variance analyses. Narrow sense heritability estimates were also computed. Four out of fifty greengram accessions were selected during preliminary screen trial based on DDd2 and DDh2 values. Two cross combinat...

Watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai] production in the United States has, in the past few years, incurred significant losses to races 1W and 2WU.S. powdery mildew (Podosphaera xanthii) infection. We report the mode of inheritance, gene action, and heritability of race 2WU.S. resistance in two populations derived from a cross involving the resistant genotype pI 189225 and the ...
Improved drought-tolerant maize hybrids would significantly reduce water consumption and increase yield in arid environments. Our knowledge about genetic parameters is very essential before starting a successful breeding program. The present research was carried out throughout three successive years between 2013-15 to reveal the pattern of inheritance in yield, yield-components and related...
Genetic components controlling a number of nutrient quality traits in rice (Oryza sativa L.) were studied using 7×7 half a diallel cross. This experiment were carried out for determination of gene action, estimation of heritability and determination the best parents. The contents of P, K, Fe, Zn and Mn were measured from white rice grain flour obtained from studied genotypes. Analysis of varian...
Early vigor is an imperative trait and its role become more important under drought stress condition. Genotypes with better early vigor cover above the soil plane, reduce evaporation of soil surface and increase weed competitiveness. In this research, a half diallel mating design was generated from crosses between seven bread wheat to study the genetic of early vigor. Parents and F1 progenies w...
The mode of agronomic traits inheritance was investigated in safflower (Carthamus tinctorius L.) in drought stress as a new report. Five generation including P1, P2, F1, F2 and F3 that derived from the cross of IL.111 (drought sensitive) ×Mex.22-191 (drought tolerance) were used in a randomized complete block design with two replic...
In order to estimate narrow-sense heritability and heterosis for phenological traits, plant height, seed yield and oil yield, F2 progenies of half diallel crosses from six varieties including RAS-3/99, RW008911, 19H, RGS003, Option500 and PF7045/91 along with their parents were evaluated in a randomized complete block design with 3 replications. Diallel analysis revealed significant mean squar...
