IDENTIFYING THE INTERREL ATIONSHIPS AMONG SEED YIELD AND ITS COMPONENTS IN LUPIN
Abstract: This investigation was conducted at Gemmeza Research Stations, Agricultural Research Center (ARC), during 2011/2012 and 2012/2013 growing seasons. To study the behavior of nine local collected genotypes and one introduced genotype compared with the one commercial genotype (Giza-1) under newly reclaimed land conditions were planted in a randomized complete block design with three replications. Results revealed significant differences among genotypes for all studied charactes. The Egyptian commercial genotype (Mutant 33) was the earliest genotypes in number of days needed to flower and recorded the height value in both number of pods/plant and number of seeds/pod with high value of seed yield/plant. Moreover, the introduced bitter indeterminate Dijon -2 which was superior in 100-seed weight and seed yield (ard./fed) with represented remarkable increases of 12.50% over the recommended check genotype Giza -1. Highly significant and positive correlation was recorded between seed yield/plant and each of plant height, number of branches, number of pods/plant, number of seeds and 100-seed weight had the greatest influence on seed yield with r values being 0.473, 0.460, 0.860, 0.913, 0.473respectively. Meanwhile, number of flowering was negative and only significant with r value -0.232 while number of maturity was positive with no significant with r value 0.029. Multiple linear regression analysis cleared that number of flowering, number of pods/plant, number of seed/plant and weight 100-seed were significantly contributed towards seed yield while the other traits did not.¬¬¬ Stepwise analysis agreed upon the number of seeds/pod (x6), 100-seed weight (x7) and plant height (x3) were accepted variables as major contribution to seed yield/plant variation 95.6% Factor analysis divided variables into three factors with 73.928% of the total variability, first factor included, plant height, number of branches/plant, number of pods/plant and number of seeds/pod accounted for 39.333% of the total variability. Second factor consisted of days to 50% flowering and 100-seed weight accounted for 18.824% of the total variability and the third factor obtained only days to maturity accounted for 15.771% of the total variability.
