ABSTRACT
An experiment entitled “To study performance of brinjal (Solanum melongena
L.) cultivars and hybrids under shade-net house conditions of western Rajasthan” was
carried out during September 2018 to March 2019 at College of Agriculture,
Mandore-Jodhpur (Rajasthan). The experiment comprised of twelve brinjal cultivars
and hybrids viz. „Pusa Hybrid-5‟, „Pusa Shyamla‟, „Pusa Hybrid-6‟, „Pusa Upkar‟,
„Pusa Kaushal‟, „Pusa Uttam‟, „Pusa Hybrid-9‟, „Pusa Anupam‟, „Soyla Local‟,
„MAHY 80‟, „MAHY Kalpataru‟ and „Sungro F1 Hybrid Brinjal No. 117‟ and was
laid out in Randomized Block Design with three replications.
Significant differences were found amongst the cultivars and hybrids of brinjal
for the studied characters. The „Pusa Hybrid-5‟ recorded the maximum plant height
(106.67 cm), while the maximum numbers of primary branches plant-1 (8.73) and
number of leaves plant-1 (288.13) were recorded in „Pusa Anupam‟. The „MAHY 80‟
produced the largest leaves (156.68 cm
2
). The „Pusa Hybrid-9‟ recorded the
maximum stem girth (49.72 mm) and plant dry weight (211.14 g), while the
maximum plant fresh weight (761.43 g) in „Soyla Local‟. The earliest first flower bud
formation (26.93 DAT) and 50% flowering (35.0 DAT) were noted in „Pusa Hybrid9‟. The „Pusa Uttam‟ produced the maximum number of clusters plant-1 (52.40), while
„Pusa Kaushal‟ produced the maximum number of flowers cluster-1 (6.93) but the
maximum number of fruits cluster-1 (1.09) was produced in „MAHY 80‟. The „Pusa
Hybid-6‟ produced the maximum number of fruits plant-1, highest fruit yield plant-1
,
highest fruit yield plot-1 and estimated highest fruit yield ha-1 (36.20, 1.65 kg, 32.21
kg and 509.69 q, respectively). The maximum fruit diameter (5.02 cm) was recorded
in „MAHY 80‟ at marketable stage and „Pusa Upkar‟ (8.59 cm) at physiological
maturity stage. The „Pusa Hybrid-5‟ had the longest fruit length at both marketable
stage (14.07 cm) and physiological maturity stage (17.07 cm). The heaviest fruits at
marketable stage were observed in „MAHY 80‟ (72.74 g) and at physiological
maturity stage in „Sungro F1 Hybrid Brinjal No.117‟ (234.0 g). Fruits of all the
cultivars and hybrids were non-spiny except „Soyla Local‟ and „MAHY Kalpataru‟.
The fruits having highest TSS (5.10 ºBrix) were noted in „Pusa Hybrid-6‟. The highest
crop growth rate was observed in „Sungro F1 Hybrid Brinjal No. 117‟ (11.71 g m-2
day-1), while the highest net assimilation rate (0.285 mg cm-2 day-1) in „Pusa Uttam‟.
The brinjal „Pusa Hybrid-6‟ resulted as the highest yielder under shade-net house
conditions in off-season of western Rajasthan providing the highest net returns (Rs.
23,332 per 500 m2 area) and B:C ratio (1.84) followed by „Pusa Hybrid-9‟and
„MAHY 80‟.
