Combining Ability Analysis for Morphological and Yield Traits in Wheat (Triticum aestivum)
Journal Title: Journal of Plant Science and Research - Year 2016, Vol 3, Issue 2
Abstract
The estimation of SCA variance was higher than GCA variance for all the characters under study which indicated that non additive genetic variance was higher than additive genetic variance for these characters. Diallel mating with recurrent selection could provide the better conditions for recombination and accumulation of desirable genes and it was recommended for such type of study. The parent “HD2888” exhibited desirable significance GCA effect for 1000 grain weight and the parent “C306” exhibited desirable significance GCA effect for 50% flowering, maturity, tillers per plant, grain yield per plant and 1000 grain weight. The best cross on the basis of SCA effect were DBW39 X PBW343 for tillers per plant, spike length, spikelet per spike, grain yield per plant and plant height and the cross C306 X K8027 for tillers per plant, spike length , spikelet per spike and grain yield per plant. These best parents and cross combinations could be effectively utilized in wheat breeding for the improvement of yield components and thus their incorporation in further breeding program was suggested.

Does Botrytis Cinerea Influence Parasitization of Myzus Persicae by Aphidius Colemani?
The dynamics of the insect herbivore and its natural enemy appears to be influenced by the presence of the pathogen. More M. persicae and parasitoids Aphidius colemani were grown on lettuce plants free from B. cinerea in...
