| dc.description.abstract | The present study was conducted during May to November 2013 at the research field of Olericulture
Division, Horticulture Research Centre, Bangladesh Agricultural Research Institute (BARI), Gazipur
to study the relationship among fruit setting and flower types and yield potentials of brinjal under
summer condition. Twelve genotypes and two varieties of brinjal viz. SM 011, SM 021, SM 58-1, SM
58-2, SM 200, SM 203, SM 204, SM 206, SM 211, SM 235, SM 236, EGN 10, BARI Begun-4 and
BARI Begun-5 were evaluated in a Randomized Complete Block Design with three replications. A
marked variation was observed among the studied genotypes regarding plant height, flowering, fruit
and yield attributes. The genotype SM 200 produced the highest plant height at final harvest (184.33
cm) with erect plant type and the lowest plant height (106.33 cm) was produced by SM 203 with
prostrate plant type. The 50% plant flowering was earlier in genotype SM 011 (48.32 days) and late
flowering was observed in SM 236 (58.10 days). The lowest number of clusters per plant (13.78) and
highest number of flowers per cluster (6.31) was recorded from the genotype SM 011. The total flower
buds per plant was recorded highest in SM 58-1 and SM 58-2 (127.62) and the lowest from SM 021
(37.31). The highest number and percentage of long styled flowers per plant counted from the
genotype SM 58-1 (82.13 and 64.35% respectively). The highest number of medium styled flower per
plant was counted from BARI Begun-4 (27.48) but highest percentage of medium styled flower was
counted from the genotype SM 200 (34.15%). BARI Begun-4 and SM 211 had the highest fruit setting
percentage 75.17% and 72.56%, respectively. The lowest fruit setting percentage was recorded from
the genotype SM 235 (30.27%). The highest yield loss per plant due to pest attacked was obtained
from genotype SM 58-2 (304.00 g) and the lowest from the genotype SM 011 (100.17 g). BARI
Begun-4 produced the maximum number of edible fruits per plant (32.13) and BARI Begun-5
produced the minimum number of edible fruits per plant (8.10). The yield per plant was found the
highest in BARI Begun-4 (2.62 kg) and the lowest in SM 011(0.92 kg). The highest individual fruit
weight (304.00 g) was obtained in EGN 10 and the lowest was 55.10 g in SM 011. The correlation
matrix exhibited that fruit yield per plant was positively correlated with number of fruits per plant
(r=0.554*), total number of flowers per plant (r=0.095), number of long styled flower (r=0.167),
number of medium styled flower (r=0.50), fruit setting percentage (r=0.442) and individual fruit
weight (r=0.335). Number of fruits per plant recorded significant positive correlation with number of
medium styled flower (r=0.692**), number of long styled flower (0.582*) and total number of flowers
per plant (r=0.577*). | en_US |
