Abstract:
An experiment was conducted at the experimental plot of Sher-e-Bangla Agricultural
University; Dhaka-1207 during the period from November 2006 to March 2007. It was
observed that out of 31 genotypes, 15 gemaypes had broad leaflet and rest 16 had narrow
leaflet. 0-1 (31 cm) and 0-2 (38cm) exhibited maximum and minimum plant height. The
highest days to 50% flowering was observed from (1-27 (98 days) and the lowest in 0-9
(63) days. Number of flower per pedunele ranged from 1.63 (0-9) to 2.75 (0-13). The
highest pod per plant was observed in 0-9 (118) and the lowest in 0-11(76). The number
of seed per plant ranged from 199 (G-14) to 156 (0-10). The number of seed per plant
ranged from 199(0-14) to 156 (0-10). The maximum, hundreds seed weight was
observed in (1-I, G-14, (3-22 (1.47g) and minimum in 0-5 (1.25g). The highest days to
maturity was observed in 0-4 (108 days) and the lowest in (i-I 5 (94days). The seed yield
per plant ranged from 6.Og ((1-24) to 3.9g (0-29). 0-1, 0-9 and 0-24 have high value for
100 seed weight; plant height. pod per plant, early 50% tlowering and seed yield per
plant. For this causes 0-1, 0-9 and 0-24, might be considered as a prospective one for
commercial cultivation as well as prospective parent in litture breeding programmed.
On the basis of morphological marker, out of 31 genotypes, 22 genotypes showed leaf
pubescence and 9 genotypes had no pubescence. Tendril formation was observed in 18
genotypes and 13 genotypes had no tendril. Both leaf pubescence and tendril formation
was observed in 11 genotypes, only leaf pubeseenecs were in II genotypes. only tendril
were in 7 genotypes and, no leaf pubescence and tendril formation was observed in 2
genotypes. Eighteen genotypes showed leaf pigmentation and 13 had no leaf
pigmentation. Stern pigmentation was observed in 22 genotypes and no pigmentation was
observed in 9 genotypes. Pod pigmentation was observed in 9 genotypes and 22
genotypes had no pod pigmentation. On the basis of seed coat colour, all the genotypes
were classi lied into Ibur colour groups. Among the genotypes. 0-1 showed black and (3-
7 showed brownish seed coat colour. Six genotypes showed dark brown and rest 23
genotype were showed light brown seed coat colour. Maximum 17 genotypes were
grouped into non-mottled and 14 genotypes were grouped into mottled testa patient On
the basis ol cotyledon colour, were genotypes classified into live di terent groups.
On the basis of genertic parameter high genotypie co-efficient of variation valuc was
observed pod per plant, plant height. days to 50% Ilowering, days to maturity. I ugh
heritability with high genetic advance was obtained from pod per plant, days to maturity,
days to 50% flowering. ('orrelation study reveled positive association of yield per plant
with seed per plant, pod per plant, hundreds seed weight. days to maturity and plant
height. Significant and positive correlation were observed in days to maturity, seed per
plant. Path analysis indicated higher number of days to maturity, hundreds seed weight
higher direct effect on grain yield. Days to 50% flowering, number of flower per
peduncle, seed per PIZLnI had positive but indirect effect on grain yield
Considering pods per plant, seeds per plant, yield, hundreds seed weight, days to
maturity, number of flower per pedtincle. BARE 11.1. 6284 (6-9). BARI lll. 5105 (G-14).
BARI 8406-129 (0-24). BARI ILX 87039 XLS ((i-IS), BARI ILL 95052 (6-22), BINA
mosure I ((j-I ) could be chosen for general cultivation or as parent in future breeding
program. Considering high heritability with high genetic advance G-27, 0-9, 0-4, 6-I5,
(i-I and 0-2 and considering significant and positive correlation 0-14 could be chosen
Ihr general cultivation or as parent in future breeding program. Identification of
morphological marker could also help for selection ofsuitahle one.
