Seed traits have been targeted by human selection during the domestication of crop species as a way to increase the caloric and nutritional content of food during the transition from hunter-gather to early farming societies. The primary seed trait under selection was likely seed size/weight as it is most directly related to overall grain yield. Additional seed traits involved in seed shape may ...

terminal heat and drought are the main constraints for wheat production in the vast and diverse semi-tropical rainfed regions of iran. high temperature stress during wheat’s reproductive stage is particularly detrimental, reducing both individual kernel weight and kernel number. identification of adapted genotypes can improve grain yield and its stability under heat stress conditions. selection...

combining ability effects were estimated for different agronomic characters in line × tester crossing program comprising 21 hybrids produced by crossing 7 lines and 3 testers. parents and hybrids differed significantly for general combining ability (gca) and specific combining ability (sca) effects, respectively. the variance due to gca and sca showed that gene action was predominantly additive...

Maize (Zea mays L.) is one of the most important crops in the world. In this study, 13 agronomic traits of a recombinant inbred line population that was derived from the cross between Mo17 and Huangzao4 were investigated in maize: ear diameter, ear length, ear axis diameter, ear weight, plant height, ear height, days to pollen shed (DPS), days to silking (DS), the interval between DPS and DS, 1...

The term kernel is derived from a word that can be traced back to c. 1000 and originally meant a seed (contained within a fruit) or the softer (usually edible) part contained within the hard shell of a nut or stone-fruit. The former meaning is now obsolete. It was first used in mathematics when it was defined for integral equations in which the kernel is known and the other function(s) unknown,...

Four sorghum hybrids (Fontanelle-625 [F-625]), Fontanelle-1000 [F-1,000], ATx631xRTx2907 [NE#20] and 5,040C) were characterized and evaluated for kernel characteristics, proximate analysis, flour characterization (particle size distributions, starch damage, amylose content and starch pasting properties) and end product in gluten-free tortilla. A commercial sorghum flour (TVM) was used as a cont...

in order to study effect of seed weight on germination and growth of wheat seedling, an experiment in seed technology laboratory of aboureihan paradise university of tehran in 2005 has been done. in this experiment, at first stage, the seeds separated by longitude step, latitude step and set frequency parameters of gravity separator set. in second stage, 10 treatments of 1000 seed weight entere...

Multiple kernel learning (Mkl) uses a convex combination of kernels where the weight of each kernel is optimized during training. However, Mkl assigns the same weight to a kernel over the whole input space. Localized multiple kernel learning (Lmkl) framework extends the Mkl framework to allow combining kernels with different weights in different regions of the input space by using a gating mode...

In this paper we consider (1) the weights of integration for which the reproducing kernel of the Bergman type can be defined, i.e., the admissible weights, and (2) the kernels defined by such weights. It is verified that the weighted Bergman kernel has the analogous properties as the classical one. We prove several sufficient conditions and necessary and sufficient conditions for a weight to be...
