Sorghum is one of the most important cereal crops in the semi-arid tropics. Several insect pests damage it. The possibility of identifying genotypes with multiple resistance to these pests and transferring the relevant genes into high-yielding varieties and hybrids has been considered as an attractive approach to reducing yield losses. A set of 12 cytoplasmic male-sterile and maintainer lines, ...

background: cardiovascular system is a very importantorgan that plays a vital role in tissue function. in farm animals,the growth and high milk production depends on function ofcardiovascular system. objectives: cardiovascular health inhigh and low-yielding dairy cows was investigated. methods:fifty 4-year-old high- yielding holstein dairy cows and fifty 4-year-old low- yielding holstein dairy ...

in order to develop a high yielding rice cultivar with optimum cooking quality, a cross was conducted between two rice cultivars khazar, high yielding and resistant to blast disease and daylamani tarom, with good cooking quality in 1990. forty pure lines were selected and compared for high grain yield in 1996. ten selected lines together with two check cultivars dasht and onda were tested in ad...

background and objectives: rice (oryza sativa) is one of the most important cereal crops and is the staple food source for over fifty percent of the world’s population. the population of rice-consuming countries is multiplying daily, and it is estimated that rice production must be increased in the coming years and an incensement in production will be the main goal of plant breeders. this has t...

Soybean [Glycine max (L.) Merrill] is an important crop in southern Africa where it cultivated a wide range of agro-ecologies. Both spatial and seasonal variability high the region. As result, breeders aim to release varieties with fine balance productivity potential stability. Genotype × environment interaction (GEI) limits selection superior genotypes heterogeneous environments consequently s...

Abstract The evaluation of the yield stability of genotypes and environment is of prime concern to plant breeders. Therefore, a comprehensive analysis of the structure of the GE interaction is needed. The objective of this investigation was to evaluate the use of sites regression (SREG) GGE methodology to stratify the pe × environment (GE) interaction in lentil. Yield data of 10 genotypes of le...

Traditional rice varieties having high flavonoids and anthocyanin traits were hybridized to high-yielding quality cultivars assess their combining ability. Significant variation was observed among parents hybrids for the studied. The predominance of non-additive gene action single plant yield, total flavonoid content, amylose whereas, trait registered additive in study. genotypes ADT 37 (R) 45 ...

Abstract One of the causes generally low upland rice productivity in Indonesia is fertility and soil pH. The use genotypes with high yielding capacity tolerant acid soils can increase productivity. This study aimed to develop an early efficient selection method, determine research was conducted using a seed germination technique on paper medium varied acidity level (pH 6.5, 5.5 4.5). Research d...
