this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
sainfoin (onobrychis viciifolia scop.) is a perennial forage legume has recognized for its feed value and high stability. this experiment was conducted to investigate the relationship among morphological and agronomic traits using multivariate statistical methods including correlation, regression and factor analysis. twenty one accessions of sainfoin were evaluated in a randomized complete bloc...
Silflower (Silphium integrifolium Michx.) has been identified as a candidate for domestication perennial oilseed crop. In order to successfully domesticate silflower it will be necessary identify traits that should targeted selection. We have conducted the first multilocation trial of replicated genotypes at six sites across four states. By observing architectural, phenological, and yield in di...
To achieve the food and energy security of an increasing World population likely to exceed nine billion by 2050 represents a major challenge for plant breeding. Our ability to measure traits under field conditions has improved little over the last decades and currently constitutes a major bottleneck in crop improvement. This work describes the development of a tractor-pulled multi-sensor phenot...
Lodging in maize, which is the result of the genotype-by-environment interactions, causes severe yield losses annually. There are many studies on lodging resistance of maize varieties now, but information about maize planting environment lodging stress is very rare. The environment lodging stress, which is a result of various factors, is characterized by uncertainty. Fuzzy sets theory and fuzzy...
Reduced height 8 (Rht8) is the main alternative to the GA-insensitive Rht alleles in hot and dry environments where it reduces plant height without yield penalty. The potential of Rht8 in northern-European wheat breeding remains unclear, since the close linkage with the photoperiod-insensitive allele Ppd-D1a is unfavourable in the relatively cool summers. In the present study, two near-isogenic...
Understanding the characteristics of carbon ion beam irradiation-induced mutation is essential to its potential application in plant breeding. A beam-mutagenized soybean population was generated from newly released variety Dongsheng 28, with irradiation dosages 100 Gy, 120 Gy and 140 Gy. Many phenotypic variations novel mutants heritable tendencies including height mutants, sterile early mature...
