heterosis for other traits revealed less heterosis for stomatal conductance, especially in water stress conditions and proved their drought tolerance. The better parent effects were higher in non-stress than stress suggested that if. Apr 19,  · Journal Full Text PDF: Identification of Heterosis and Nature of Gene Action in Bread Wheat Under Normal and Drought Stress Conditions. Abstract The effects of drought stress on heterosis and the component of genetic variances were investigated using half diallel mating design among eight bread wheat cultivars. Hybrid wheat technology can play an effective role in enhancing grain production. Although the presence of heterosis in wheat was earlier reported in by Freeman, its large scale exploitation had not been realized to recent past. Studies on heterosis would help for generating breeding strategies of hybrid wheat production.

Heterosis and heterobeltiosis studies were done at Department of Plant Breeding and Genetics, University of Agriculture, Faisalabad, Pakistan following Matzinger’ approach () among seven wheat genotypes viz., Shahkar, Parwaz, Iqbal, Uqab- , MH, and Punjab for crosses in all possible combinations. heterosis for other traits revealed less heterosis for stomatal conductance, especially in water stress conditions and proved their drought tolerance. The better parent effects were higher in non-stress than stress suggested that if. Hybrid wheat technology can play an effective role in enhancing grain production. Although the presence of heterosis in wheat was earlier reported in by Freeman, its large scale exploitation had not been realized to recent past. Studies on heterosis would help for generating breeding strategies of hybrid wheat production. Dwarfness is desirable trait for wheat crop hence negative heterosis is favourable to avoid lodging thus producing stable yield. The cross K x NW (%) showed highest relative heterosis in normal condition, crosses AAI x K- and NW x K ( Author: Saurabh Dixit, Rm Tripathi, V Prasad, Kumud Singh. Heterosis and combining ability analysis in bread wheat [Triticum aestivum L.] Significant heterosis over economic parent and mid parent was observed for almost all the traits, studied. The magnitude of heterosis was highest ( %) for number of spikelets per spike over economic parent and for number of tillers per plant ( %) over mid parent. Heterosis is the increase or decrease in vigour of hybrids when com- pared with that of its parents (Sharif et al. ). Exploita- tion of heterotic effects is mainly accredited to cross- pollinated crops but now-a-days the incidence is common in self-pollinated crops such as wheat (Singh et al. ; Akbar et al. benefits from heterosis in a hybrid wheat program. The impact of heterosis in wheat has not received the level of attention seen in other crops, particularly maize. Although wheat is a self-pollinated species, reports of the yield benefit in hybrids range from 5% to over 20%, depending on . HETEROSIS FOR YIELD IN BREAD WHEAT. Kernel number per spike: Kernel number increased in all crosses over mid parent and in 13 crosses over better parent. Significant heterosis values of 14 crosses and heterobeltiosis values of 6 crosses were estimated (Table 4). Heterosis Analysis in F1Hybrids of Bread Wheat Heterosis and Heterobeltiosis Analysis for Spike and its Related Attributes in Different Wheat Heterosis for yield and its components in bread wheat crosses among powdery mildew resistant COMBINING ABILITY IN .

Abstract The effects of drought stress on heterosis and the component of genetic variances were investigated using half diallel mating design among eight bread wheat cultivars.Abstract: A 6 × 6 parent full diallel set of bread wheat (Triticum aestivum L) was studied for better parent and standard variety. The magnitude of heterosis from. mildew resistant wheat lines derived from CIMMYT and three susceptible commercial wheat methods for this purpose is heterosis in other words hybrid vigor. of heterosis in spring wheat.
