Abstract
The investigation entitled “Evaluation of seedling progenies of charoli
(Buchanania lanzan Spreng) for their yield and quality under North Eastern transitional
zone of Karnataka” was carried out at Kolar village of Bidar district during 2018-19.
Among the 50 seedling progenies selected for the study, all the genotypes are
early bearing in nature except KCS-6. The maximum fruit yield per tree was recorded in
KCS-43 (6.39 kg). The maximum fruit weight (1.48 g) and pulp weight (1.10 g) were
recorded in KCS-22. The maximum shelling percentage of charoli nuts was recorded in
KCS-34 (34.87 %) while, the maximum kernel weight was recorded in KCS-2 (0.10 g).
Regarding the quality parameters of charoli, the maximum TSS (24.00 °B) and total
sugars (15.87 %) were recorded in KCS-16 while, the maximum titrable acidity was
recorded in KCS-15 (0.68 %). With respect to kernel quality parameters, the maximum
protein percentage in kernel was recorded in KCS-27 (20.69 %) and the maximum fat
content in kernel was recorded in KCS-7 (40.69 %).
Yield attributing characters viz., number of panicles per plant, number of fruits
per panicle and kernel weight had shown significant and positive correlation with yield
per tree (0.746, 0.647 and 0.320 respectively) and there is no significant correlation
between plant spread (East-West and North-South), leaf area, fruit weight and nut
weight (-0.161, 0.003, 0.033, 0.074 and 0.098 respectively). Quality parameters viz.,
TSS, titrable acidity, protein, fat and total sugars didn‟t show any significant correlation
for yield. There is positive and significant correlation between TSS and total sugars
(0.714) and protein and number of fruits per panicle (0.372).
KCS-27, KCS-33, KCS-43 and KCS-46 seedling progenies were found superior
for yield and quality attributes. They can be utilized in the future crop improvement
programme.
