Abstract

The study aimed to assess the fresh harvest and physiological maturity of
red long bean lines at several harvest ages. The study was conducted in
Sumbersoko Village, RT.10/RW.01, Sukolilo, Pati and the Plant Physiology and
Breeding Laboratory, Faculty of Animal and Agricultural Sciences, Universitas
Diponegoro, from November 2024 to February 2025.
The research design used was a split plot design applied to a randomized
block design with 7 F7 generation long bean lines (FA 1–1–4–3–6–8–B, FS 3–4
7–1–B, FA 3–2–13–14–B, FA 1–1–5–3–18–B, FA 1–1–10–1–6, FS 3–4–10–3
B And FS 3–4–8–2–B), elders long beans (Fagiola IPB and Aura Hijau) as the
main plot, and harvest time (8, 11, 14, 17, 20, 23, 26, 29, 32 And 35 day after
anthesis (HSA)) as a child plot. Test repeated 3 time, parameter Which observed
that is long pods, fresh weight of pods/plant, number of pods/plant, number of
seeds/pod, germination capacity, seed water content, sweetness level, pod shelf
life, pod shape, texture pod, color pod, color end pod, color seed main, secondary
seed color and seed shape. Qualitative data were analyzed descriptively,
quantitative data were analyzed descriptively. use Analysis of Variance Which to
be continued test Different Real Honesty level 5%, as well as correlation analysis
and path analysis.
The results of the study indicate that the lines have different qualitative and
quantitative characteristics at certain harvest ages. Fresh harvesting produces red
purple pods ( greyed-purple group RHS 187 and purple group RHS N77) with
end pod green yellowish ( yellow-green RHS group 145), while harvesting Cook
physiological own color pod And color end pod brownish ( brown group RHS
200). All producing strains seed color main and seed color secondary Which
different. Line influential significant to The parameters were pod length, fresh pod
weight/plant, number of pods/plant, seed weight/pod, and sweetness level. Harvest
age had a significant effect on all parameters. The interaction between strain and
harvest age had a significant effect on weight fresh pods/plants, amount
pods/plants, Power germination, and sweetness level. A significant correlation and
contribution were shown between sweetness level and the shelf life of fresh pods,
as well as water content with germination power and seed number. The conclusion
of this study is that there is a significant effect of harvest age on the shelf life of
fresh pods. 8 And 11 HSA on 2 strain, 11 And 14 HSA on 3 strain, harvest 11 HSA
on 1 line and harvest 8, 11 and 14 on 1 line. Physiologically ripe harvesting can be
done age 20, 23 And 26 HSA on 3 strain as well as 20 And 23 HSA on 4 strain.
