Abstract
This investigation was conducted at Ismaitrcrcmd Abo-Simbie Research Stations during 2000/2001 and 2001/2002 growing seasons to study the behaviour of nineteen local collected genotypes and three introduced varieties compared with the two commercial varieties (Giza-1 and Giza-2) under newly reclaimed land conditions. In addition to study the relative contributing of yield factors of white lupin. Genotypes were planted in a randomized complete block design with three replications.
Results revealed significant differences among genotypes for all studied characters. The introduced sweet determinates Kiev Mutant and Piscevoj were the earliest.genotypes in number of days needed to flower and mature, but they exhibited the lowest values of seed yield at both locations. The local genotypes Belbies-9 and Family-9 were most promising for productivity and out yielded the recommended check variety Giza-1 by 22.86 and 13.88%, respectively, at Ismailia. Meantime, the local genotypes Ismailia-2 and Algeerb-2 were the most promising ones and yielded 33.78 and 32.28%, respeCtively, more than the recommended check variety Giza-2 at Abo-Simble. Moreover, tlie introduced bitter indeterminate Dijon-2 which retained its potentiality over the two different environmental conditions was superior in seed yield and represented remarkable increases of 20.88 and 38.79% over the recommended check variety Giza-1 at Ismailia and Giza-2 at Abo-Simble, respectively. Kiev Mutant and Piscevoj gave the lowest percentage of seed alkaloid, while Gerga-2 and Dijon-2 contained the highest seed alkaloid percentage.
Highly significant and positive correlation was recorded between seed yield/plant and each of days to 50% flowering, days to maturity, plant height, number of branches/plant, number of pods/plant and number of seeds/pod at both Ismailia and Abo-Simble. Meanwhile, 1 ~O-seed weight and alkaloid% were Significant positive correlation with seed yieldlplant at Ismailia. Plant height, number of pods/plant, number of seeds/pod and 1 ~O-seed weight were the most important contributing factors to seed yield at Ismailia (R2 = 84.4%). At Abo-Simble, number of pods/plant, 100-seed weight, number of seeds/pod and days to maturity were accepted variables as significant contributors to the variability of the seed yield/plant (R2 = 70.3%). According to path analysis, number of pods/plant, plant height and number of seeds/pod had the greatest direct effects towards seed yield at Ismailia. While, at Abo-Simble, number of pods/plant, 1 Ou-seec weight and number of seeds/pod proved to have the highest direct contribution to seed yield. Whereas, days to maturity showed positive indirect contribution towards seed yield variation, at both location.
