Hazelnut (Corylus avellana L.) is the one of the native and valuable shrub in Iran. Identification of the superior genotypes of hazelnut is the firs step for cultivation developing and breeding programs of this nut crop. In this research, had been studied phenological, morphological and pomological characters according to hazelnut’s descriptor for two years (2009-2010) on four populations of ha...

In agricultural experimentation, a large number of genotypes are normally tested over a wide range of environments (locations, years, growing seasons, etc.) and the underlying statistical and genetical theories used to model this system may be rather complicated. The occurrence of the genotype (G) X environment (E) interaction effect further complicates the selection of superior genotypes for a...

This research aimed to determine the potentiality of P1 and P2 as parents produce superior strains hybrid cacao by estimating general combining ability (GCA) specific from crossed diallel among high yielding which are resistant P. palmivora . The study was conducted at Experimental Farm Sumber Asin, Malang, East Java, 2010 2018. arranged in Randomized Block Design (RBD) consisted 10 hybrids 5 s...

Cotton is India’s most important cash crop and it used for agricultural industrial purposes all over the world. The greatest way identifying superior hybrids best combiners of parents by L×T design. For analyzing combining ability heterosis various yield attributing variables as well quality traits, viz., four lines testers were crossed to produce sixteen hybrids. MCU5 × KC3 cross contributed p...
