Background: Indian mustard is an important oilseed crop which occupies premier position in agriculture. Developing high yielding genotypes a major breeding objective mustard. Present study was conducted at Experimental Farm of Ranaghat, Nadia, West Bengal, during 2017 to 2019. Methods: Line x tester analysis seven lines and five testers carried out identify the heterotic crosses their relations...

Drought and poor soil fertility are among the major abiotic stresses affecting maize productivity in sub-Saharan Africa. Maize breeding efforts at the International Maize and Wheat Improvement Center (CIMMYT) have focused on incorporating drought stress tolerance and nitrogen-use efficiency (NUE) into tropical maize germplasm. The objectives of this study were to estimate the general combining ...

BACKGROUND Combining ability effects are very effective genetic parameters in deciding the next phase of breeding programs. Although some breeding strategies on the basis of evaluating combining ability have been utilized extensively in hybrid breeding, little is known about the genetic basis of combining ability. Combining ability is a complex trait that is controlled by polygenes. With the ad...

The study aimed to show the best effect of general combining ability (GCA) and specific (SCA) for parents their hybrids studied traits. included two main successive seasons. In first season, cherry tomato pure lines were selected that introduced from Tomato Genetics Resource Center (TGRC) at University California, Davis in USA, 5 which most genetically Distant are (LA4451, LA4753, LA3334, LA122...

An experiment was carried out with North Carolina Mating Design II (NC II) derived F1 progenies along parents to know nature of gene action in regulating early maturity, yield and contributing traits. The principal objective this research identify best specific cross combinations based on combining ability analysis estimation heritability. Hybrids their were arranged a 8 by partially balanced l...

satureja rechingeri, belonging to the family lamiaceae, has been recently used in the pharmaceutical industry due to its high level of carvacrol in the essential oil. the domestication and breeding of suitable s. rechingeri variety has been started since few years ago in iran. the initial screening of natural populations, grown in the same environment, was performed and 58 talent clones were se...

to study general combining ability (gca) and estimation of heterosis in sunflower inbred lines for seed yield and other three agronomic traits, 68 inbred lines crossed with open pollination variety lakumka. in next year inbred lines along with topcrosses were planted in rcbd with 2 replications under two moisture conditions in sararood agricultural research station. analysis of variance in both...

Background: A study was carried out to estimate the general and specific combining abilities, as well heterosis for seed yield associated traits in pea lines. Methods: Twenty-eight cross combinations were generated using half-diallel mating design with eight parental The mean values of its contributing lines their offspring each replication used statistical analysis viz., GCA, SCA Heterosis. Re...
