On the basis of two years pooled data analysis, various growth and yield parameters showed significant differences which are stated and discussed in the following heads:
Growth parameters
Days taken to 50% seed germination
The pooled analysis results stated in Table 1, revealed that the minimum days taken to 50% seed germination was observed in T
9 (8.17; IC-265934) that was statistically
at par with T
13 (8.67; IC-278508) and T
14 (9.00; IC-328626). Whereas, the maximum days was recorded in T
17 (14.00; IC-341856) which was statistically
at par with T
1 (IC-037145) and T
19 (IC-341860) with standing the similar mean value as 13.17 days. This result might be due to the presence a sufficient amount of soil moisture, soil temperature, seed viability, genetic variability within the genotype itself. Previously, the similar differences were reported by
Subedi et al., (2022).
Germination percentage (%)
On the basis of pooled analysis (Table 1), the maximum germination percentage was observed in T
6 (95.40%; IC-043572), while the minimum germination percentage was recorded in T
11 (69.28%; IC-274530). This result might be due to bold seeded nature of some of the genotypes. Similar finding was reported by
Kalauni et al., (2020).
Plant height at 30 DAS, 45 DAS and at final harvesting stage (cm)
It was clearly obvious from the pooled data tabulated in Table 1, that there was a significant difference in plant height among French bean genotypes. The maximum plant height at 30 DAS was measured in T
6 (17.85 cm; IC-043572), followed by T
16 (16.16 cm; IC-341851). Whereas, the minimum height was observed in T
9 (8.53 cm; IC-265934), that was statistically
at par with T
11 (9.51 cm; IC-274530). The highest mean value at 45 DAS was recorded in T
6 (35.02 cm; IC-043572) and the minimum was observed T
9 (18.01 cm; IC-265934) and at the final harvesting stage maximum height was in T
6 (42.51 cm; IC-043572), followed by T
4 (40.57 cm; IC-037172), whereas, minimum was observed in T
9 (25.87 cm; IC-265934). The disparity in plant height may be due to genetic differences among the genotypes. The results of present findings were in agreement with
Zelaing et al., (2018) and
Akter et al., (2021).
Number of leaves at 30 DAS, 45 DAS and at final harvesting stage
The pooled data results presented in Table 1, clearly stated that the maximum number of leaves was noticed in T
6 (25.69; IC-043572), followed by T
5 (22.93; IC-043557) at 30 DAS. Whereas, the minimum was observed in T
11 (7.12; IC-274530), which was statistically
at par with T
9 (8.57; IC-265934). The highest mean value at 45 DAS was in T
6 (54.65; IC-043572), that was statistically
at par with T
10 (51.37; IC-265941) and T
5 (49.74; IC-043557), while the least number of leaves was observed in T
11 (24.47; IC-274530), which was
at par with T
20 (28.81; IC-341868) and T
16 (26.83; IC-341851). The maximum number of leaves at final harvesting stage was recorded in T
6 (100.48; IC-043572), whereas the minimum was observed in T
11 (62.70; IC-274530), which was statistically
at par with T
20 (65.15; IC-341868). This result might be due to environmental effects and photosynthetic activity of the plant. Similar results were documented by
Akter et al., (2021).
Fresh and dry weight of root per plant (g)
Perusal of the data presented in Table 1, revealed that the maximum fresh weight of root per plant was found in T
6 (13.58 g; IC-043572) followed by T
17 (11.74 g; IC-341856), while the minimum was recorded in T
13 (3.43 g; IC-278508) followed by T
18 (3.91 g; IC-341858) whereas, the maximum dry weight of root per plant was observed in T
6 (5.80 g; IC-043572) and minimum was recorded in T
13 (1.63 g; IC-278508) which was found statistically
at par with T
19 (1.83 g; IC-341860), T
3 (2.05 g; IC-037169) and T
18 (2.15 g; IC-341858).
Fresh and dry weight of shoot per plant (g)
From the analyzed pooled data (Table 1) related to fresh and dry weight of shoot per plant a significant variation was observed in French bean genotypes. The highest fresh weight/plant was noticed in T
6 (113.96 g; IC-043572), while, the minimum was observed in T
9 (42.10 g; IC-265934) and maximum dry weight of shoot/plant was noticed in T
6 (88.53 g; IC-043572), whereas, the minimum was found in T
9 (20.57 g; IC-265934). These results were in agreement with
Barcchiya and Kushwah, (2017).
Yield parameters
Days taken to 50% flowering
On the basis of pooled data, as presented in Table 2, revealed that the minimum days taken to 50% flowering was observed in T
9 (34.17; IC-265934), which was statistically
at par with T
4 (34.50 days; IC-037172), T
11 (34.33 days; IC-274530) and T
13 (35.33 days; IC-278508). In contrast, the maximum days were recorded in T
17 (42.17; IC-341856) which was
at par with T
2 (IC- 037156) and T
19 (IC-341860) that were having same mean value as 40.83 days and T
15 (41.83 days; IC-341850). The differences in flowering duration may be ascribed to genetic disparity, these findings were corroborated with the findings of
Das et al., (2018).
Pod length (cm)
On the basis of pooled data analysis (Table 2), the maximum pod length was measured in T
6 (14.68 cm; IC-043572), whereas, the minimum was in T
12 (7.68 cm; IC-278499). Similar findings were reported by
Zelaing et al., (2018) and
Whankate et al., (2021) in French bean.
Pod diameter (cm)
The highest mean value of pod diameter was noticed in T
2 (1.24 cm; IC-037156), followed by T
3 (1.04 cm; IC-037169) and T
7 (IC-264259) and T
8 (IC-265910) which were having same mean value as 1.03 cm (Table 2). While, the minimum was found in T
16 (0.63 cm; IC-341851), that was
at par with T
10 (0.67 cm; IC-265941), T
11 (IC-274530) and T
17 (IC-341856) that were standing with same mean value of 0.68 cm, T
14 (0.71 cm; IC-328626) and T
20 (0.72 cm; IC-341868). This result might be due to their inherited traits and to some extent by environmental factors. The present findings were in close conformity with the results reported by
Das et al., (2018).
Weight of individual pod per plant (g)
The results tabulated in Table 2, showed that the maximum weight of individual pod was recorded in T
6 (5.65 g; IC-043572), followed by T
11 (4.58 g; IC-274530), whereas, the minimum was found in T
7 (2.03 g; IC-264259), which was
at par with T
2 (2.65 g; IC-037156), T
5 (2.47 g; IC-043557), T
18 (2.79 g; IC-341858) and T
21 (2.68 g; Falguni). The present findings were in close conformity with
Panchbhaiya et al., (2017) and
Whankate et al., (2021) in French bean.
Green pod yield per plant (g)
On the basis of pooled analysis (Table 2), it was found that T
6 (IC-037156) recorded with the highest (205.50 g) green pod yield which was statistically
at par to T
15 (194.06 g; IC-341850), while the minimum measured in T
21 (93.17 g; Falguni), which was at par with T
1 (94.11 g; IC-037145), T
2 (97.75 g; IC-037156), T
3 (98.02 g; IC-037169) and T
11 (104.71 g; IC-274530). It might be due to indirect contribution on total association of number of branches/plant and plant height. This result was in agreement with
Devi et al., (2015) and
Kumar (2022).
Green pod yield per hectare (t)
The pooled analysis of this parameter as tabulated in Table 2, revealed that the maximum yield was recorded in T
6 (59.51 t; IC-037156), that was
at par with T
13 (54.78 t; IC-278508), T
15 (57.13 t; IC-341850) and T
16 (53.48 t; IC-341851), whereas, the minimum yield was observed in T
21 (26.58 t; Falguni), which was statistically
at par with T
1 (26.92 t; IC-037145), T
2 (28.20 t; IC-037156), T
3 (28.39 t; IC-037169), T
9 (26.62 t; IC- 265934) and T
18 (32.35 t; IC-341858). This result was attributed to better root proliferation, good uptake of nutrients and water, high photosynthetic activity and enhanced food accumulation. These results were close in conformity with
Whankate et al., (2021) and
Thapa et al., (2022).
