LINE X TESTER ANALYSIS OF COMBINING ABILITY IN COTTON
Madras Agricultural Journal, 1995In a line x tester study of cotton (Gossypium hirsutum L.) involving 11 lines and 3 testers. (33 hybrids), it was found that all the characters studied (i.e., plant height, humber of monopodia. days to 50% flowering, days to 50% boll bursting, boll weight and yield of seed cotton) are controlled by additive but predominantly non-additive gene action ...

Line x Tester Analysis in Rice (Oryza sativa L.)
Madras Agricultural Journal, 2010One hundred and fifteen crosses from five CMS lines and 23 restorers along with parents were evaluated in line x tester design for grain yield and yield components in rice. Predominance of non additive gene action was observed for all the characters, suggesting the development of hybrids in rice.

LINE X TESTER ANALYSIS IN SESAME (Sesamum indicum L.)
Madras Agricultural Journal, 1990In a line x tester analysis involving 15 lines and 4 testers in sesame (Sesamum indicum L.), combining ability was estimated for nine traits. Predominance of SCA variance over GCA variance indicated that these traits might be controlled predominantly by non additive gene action. Biparental mating followed by recurrent selection might hasten the rate of

Line X Tester Analysis in Rice (Oryza sativa L.)
Madras Agricultural Journal, 2012Line x tester analysis using a set of three females (Lines) and eight males (testers) was carried out to estimates the extent of combining ability for yield and its components in rice (Oryza sativa L.). Experimental material comprising eleven parents, their twenty four hybrids were planted in a randomized block design with three replications during ...

LINE X TESTER ANALYSIS FOR HEAVY SEEDS IN CHICKPEA
Madras Agricultural Journal, 1993To know the combining ability of seed weight in chickpea, five lines namely Co. Coz, CoG4, CoG6 and ICCV2 as females and three testers namely Annigeri, Cos and L 550 as males were crossed in a line x tester model. The effects of the parents and the sca effects of the hybrids were estimated.

LINE X TESTER ANALYSIS OF COMBINING ABILITY IN GROUNDNUT
Madras Agricultural Journal, 1994A line x tester analysis was carried out involving eleven lines and two testers in groundnut for assessing the combining ability in respect of number of pods, pod yield, harvest index, shelling outturn and sound mature kernels. The estimate of GCA/SCA variance showed the predominance of non-additive gene action for number of pods and pod yield.

Line X tester analysis in sesame (Sesame indicum L.)
Madras Agricultural Journal, 2002Line x tester analysis (14 x 3) of combining ability revealed preponderance of non- additive gene action for seed yield and its components. Guj. Til 1, Sel. 73, Sel. 33, Sel. 123 and Uma were good general combiners for seed yield and yield contributing characters.

LINE X TESTER ANALYSIS FOR COMBINING ABILITY IN SALINE RICE CULTIVARS
Madras Agricultural Journal, 1997Combining ability for eight quantitative characters in saline rice cultivars was studied through Line X Tester analysis involving five saline susceptible lines and seven saline tolerant testers. The combining ability analysis revealed that variance due to lines x testers was significant for all the eight characters studied. The estimates of osca, o gca
