In order to study the adaptation of rice lines to drought stress and to identify the tolerant and sensitive lines, 150 pure lines in RIL population each derived from a cross between two Iranian rice varieties Gharib and Sepidroud were investigated. Augment design based on the randomized complete block design (RCBD) was used with 6 check cultivars and 4 replications in 2013-2014 growing season. ...
the complexity of the genetic control of drought tolerance makes inevitable using of molecular methods with biometric approaches to its improvement in plants. present study was conducted by 121 advanced lines and varieties of soybean under two moisture levels, normal and drought stress with 21 microsatellite markers linked to drought tolerance in two regions, namely, rasht and gonbad-kavous. gr...
the selection of high yielding varieties with good stability is an important objective in rice breeding programs. the grain yield of eight rice lines with a check (nemat) were compared on six locations of gilan and mazandaran provinces during two years, using rcbd with four replications. combined analysis of variance showed that the effect of variety and year × location × variet...
Genetic diversity of 13 new cereals, primary tritipyrum lines, five triticale lines and nine Iranian bread wheat varieties was studied under the randomized completely blocks design in terms of agronomic and morphological traits. The highley significant difference was observed between genotypes for all traits except in the filamental leaf length, main leaf length and main leaf width. The highest...
The English grain aphid, Sitobion avenae, is a major pest species of wheat crops; however, certain varieties may have stronger resistance to infestation than others. Here, we investigated 3 classical resistance mechanisms (antixenosis, antibiosis, and tolerance) by 14 wheat varieties/lines to S. avenae under laboratory and field conditions. Under laboratory conditions, alatae given the choice b...
Among the superior varieties can be obtained through breeding. The low level of farmer adoption improved resulting from breeding is partly due to different preferences farmers with development specific will successful a participatory program that involves breeders, and rice industry players in selection process for prospective new varieties. research objective was analyze select quantitative qu...
