Determination of Some Agricultural Characters and Their Heredity Through Line X Tester Method in Dry Bean (Phaseolus vulgaris L.)

In this study, the crosses by line x tester (18 hybrid combination) between six bean lines (pv04035, pv04086, pv04092, pv04145, pv05001 and pv05023) and commercial dry bean cultivars (great northern 59 and alberto) and one runner bean (phaseolus coccineus l.) were made in 2017. the f1 hybrids together with the parents were evaluated in fully-automated plant breeding greenhouse of selcuk university in 2018. measurements, counts and weightings were determined plant height, number of pods per plant, number of seeds per pod, number of seeds per plant, hundred-seed weight and plant seed yields of the parents and hybrids. for investigated traits, line x tester analysis method was employed to determine general combining ability (gca) and specific combining ability (sca), heterosis and heterobeltiosis values, broad and narrow sense heritability among the investigated traits of the parents and hybrids.in the study, general combination ability of pv04145 and phaseolus coccineus l. lines is high in seed yield. the specific combining abilitiesof the “pv05023 x p. coccineus l.” were found to be high. in the seed yield, heterosis values were determined as -11.97% (pv05001 x p. coccineus l.) and 39.35% (pv04086 x great northern 59). the fact that the analyzed material shows heterosis in terms of seed yield and the average yield values are high, it shows that this material can meet the needs of high yielding variety candidates in terms of the central anatolia region.
