Combining ability of tropical and temperate inbred lines of popcorn.
In Brazil, using combining ability of popcorn genotypes to achieve superior hybrids has been unsuccessful because the local genotypes are all members of the same heterotic group. To overcome this constraint, 10 lines (P(1) to P(10)) with different adaptations to tropical or temperate edaphoclimatic environments were used to obtain 45 F(1) hybrids in a complete diallel. These hybrids and three c...
متن کاملgeneral and specific combining ability of some sunflower inbred lines and restorers
in order to produce new hybrids and evaluate the general and specific combining ability of sunflower inbred lines and restorers, four inbred lines and six restorers were selected in 2004. twenty-four f1 hybrids were derived in 2004 and evaluated on a rcbd design with three replications in 2005. the results of variance analysis showed that treatments were significantly different for all traits e...
متن کاملCombining Ability among Twenty Insect Resistant Maize inbred lines Resistant to Chilo partellus and Busseola fusca Stem borers
A partial diallel design was used among 20 maize inbred lines to form 110 F1 hybrids to generate information on the values of these lines for developing insect resistant maize varieties during the short rains season of 2006. The hybrids were evaluated for resistance to the C. partellus and B. fusca, and for agronomic performance over two seasons during long and short rains of 2007 at a mid-alti...

general and specific combining ability of five fertile male (lines) and two male sterile (tester) of rice were evaluated for 10 important morphological traits as well as yield and yield components in a randomized complete block design with three replications. results revealed that general combining ability effects were highly significant (p
متن کاملstudy on general combining ability of inbred lines and heterosis of sunflower crosses in different moisture conditions
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...
