Abstract:

Mean positive correlation (r = 0,47**) between grain yield and number of plants per m? and strong correlation between grain yield and number of spikes per m? were established (r = 0,55**). Weak correlation was established between grain yield and productive tillering (r = 0,24**). Strong positive correlation (r = 0,51**) is between the number of spikes per m? and productive tillering, as well as between the number of plants per m? and number of spikes per m? (r = 0,68**). Very weak negative correlation (r = -0,12*) is between productive tillering and the number of plants per m?. Regression equa

Abstract:

The purpose of the present study is to identify breeding and genetic peculiarities for productive tillering in spring barley genotypes of different origin, purposes of usage and botanical affiliation, as well as to identify effective genetic sources to further improving of the trait. There were created two complete (6 × 6) diallel crossing schemes. Into the Scheme I elite Ukrainian (MIP Tytul and Avhur) and Western European (Datcha, Quench, Gladys, and Beatrix) malting spring barley varieties were involved. Scheme II included awnless covered barley varieties Kozyr and Vitrazh bred at the Plant

Abstract:

Pearl millet (Pennisetum glaucum (L.) R. Br.) is commonly grown at a wide range of plant population densities, both by design and as a consequence of stand establishment problems. High tillering genotypes are known to compensate effectively for lower plant population densities through their tillering capacity; less is known about the ability of naturally low tillering genotypes to adjust to low plant population densities. This is a particular concern in the case of the Iniadi landrace materials which are currently widely used in breeding programmes in both India and Africa. This research was d

Nitrogen applied at 150 kg/ha before sowing did not increase grain protein concentrations, 300 or 400 kg/ha of N being needed. Nitrogen applications before sowing and during tillering were usually more effective in promoting yield than dressings applied after tillering or applied as several suboptimal dressings between tillering and flowering.

According to their observations the value of field emergence is always lower than the laboratory germination. The weak emergence is important because the lower plant density cannot be compensated by the increased tillering in spite of having larger plant growth space.

Abstract:

A tiller number is the key determinant of rice plant architecture and panicle number and consequently controls grain yield. Thus, it is necessary to optimize the tiller number to achieve the maximum yield in rice. However, comprehensive analyses of the genetic basis of the tiller number, considering the development stage, tiller type, and related traits, are lacking. In this study, we sequence 219 Korean rice accessions and construct a high-quality single nucleotide polymorphism (SNP) dataset. We also evaluate the tiller number at different development stages and heading traits involved in pha

Abstract:

Transient waterlogging during winter and spring reduces wheat yield in many parts of southern Australia. Yield reductions from waterlogging are associated with reduced production and survival of tillers, fewer and smaller fertile tillers, and smaller grain size. Under favourable conditions, wheats that have the tiller-inhibition ('tin') gene produce a lower total number of tillers but a higher proportion of large, productive tillers and larger grains than wheats without this gene. These characteristics of restricted-tillering wheat may contribute to improved yield under transient waterlogging.

Additional yield in variants with inoculation and under N60P60K60 dose of fertilizer was 0.5 t/ha. It was established that yield increase was obtained mainly due to the higher grain mass and index of productive tillering.

It is known that the optimal density of the productive stem should be formed in one case by increasing the density of standing plants, in the other – the intensity of tillering. With the deterioration of plant development conditions, tillering plays an increasingly smaller role and the density of standing plants, therefore, the seeding rate, plays an increasing role. A decrease in the seeding rate leads to better crop blowing and a logical decrease in the infectious background. This is extremely important in wet years, when there is a high probability of damage by leaf spots. In thickened crop
