and steady crop growth of genetic character of the particular clone in ratoon crop. The clone Si 94045 exhibited higher cane yield of 127.5 t/ha and it was comparable with Si 94050, which recorded 124.3 t/ha even though these two clones are statistically superior to the rest of the entries in plant crop. The commercial cane sugar per cent indicated significant results. The clone Si 94045 recorded maximum commercial cane sugar per cent of 11.6 and it was comparable with the clones C 95111, Si 94050 and Co 86032 which recorded 11.2, 11.6 and 11.4 per cent respectively in plant crop. Significant results were also noticed in sugar yield in plant crop. Clone Si 94045 recorded higher sugar yield of 14.5 t/ha and it was on par with the clone Si 94050 (14.2 t/ha). Ratoon trial showed significant differences among clones/varieties. Clone Si 94050 produced maximum cane yield of 125.6 t/ha and it was at par with the clone Si 94045 (121.6 t/ha). These two clones were statistically superior to the other entries. The clone Si 94045
exhibited higher commercial cane sugar per cent of 11.6. Clone Si 94050 recorded highest sugar yield of 13.6 t/ha and it was on par with the clone Si 94045 (13.5 t/ha) in ratoon crop. From the results the identified as a superior and ratoon crop, which yield, commercial cane sugar yield.
clone Si 94045 was clone in both plant showed higher cane sugar per cent and
It is non-lodging, non flowering and moderately resistant to red rot disease. Hence this clone may be used for cultivation under early maturing condition. References Gomez, K.A. and Gomez, A.A.

Effect of harvest at different days after fruit set on fruit quality and shelf life of bhendi (Abelmoschus esculentus (L) Moench) G. BALA HUSSAINI AND K. HARI BABU Agricultural Research Station, Anantharaju pet-516105, Research Station, Anantharaju pet-516105, Bhendi is one of the important vegetable crops in India. Tender green, immature and fibreless fruits are cooked to a delicacy. As days after fruit set increased, the fibre content
in bhendi fruits will be increased and fruits became tough and tenderless. Fibre rich fruits have less cooking and marketable value. Standaridization of maturity indices for harvest

in bhendi is not given much importance. Hence, the present investigation is carried out to study the effect of harvest at different days after fruit set, on quality and shelf life of bhendi cultivars viz. Parbhani Kranthi and Arka Abhay Materials and Methods Bhendi cuitivars Parbhani Kranthi and Arka Abhay were raised during kharif 2000. The experiment was laidout in factorial RBD with 3 replications. The fruits were harvested on 3, 5, 7, 9 and 11th day after fruit set and observations on fresh and dry weight of fruits, fruit length and diameter, fibre content in fruits, visual spoilage and shelf life were recorded and statistical analysis was done as suggested by Panse and Sukhatme (1985). Results and discussion The effect of days of harvest after fruit set in bhendi cultivars viz. Parbhani Kranthi and Arka Abhay on different parameters is presented in table1& 2. The fresh weight of fruits varied significantly among days of harvest after fruit set and varieties (Table -1) The fresh weight of fruits showed increasing trend from 3 to 11 days of harvest after fruit set in both the varieties of bhendi. It was observed that maximum fresh weight of fruit was accumulated from 9 to 11 days of harvest after fruit set. Similar trend of increasing dry weight of fruits was also noticed in both the varieties of bhendi. But fruits of Parbhani Kranthi accumulated the maximum dry weight from 9 to 11 days after fruit set, whereas fruits of Arka Abhay accumulated the maximum dry weight from 7 to 9 days of harvest after fruit set. The fruit length and diameter varied significantly among the days of harvest after fruit set but a non-significant variation was observed among the varieties (Table -1). The fruits of both varieties recorded maximum fruit length and diameter at 11th day harvest after fruit set.
The effect of days of harvest after fruit set on fibre content of fruits is presented in Table -2. Among the varieties Parbhani Kranthi exhibited maximum mean fibre content of fruits (0.82%) when compared to Arka Abhay (0.70%). But both varieties of bhendi accumulated maximum fibre content in fruit from 5 to 7 days of harvest after fruit set. Similar results in bhendi were reported by Salmon (1983). Fruits harvested at 7th day after fruit set exhibited minimum percentage of visual spoilage during storage in both the varieties (31.5% in case of Parbhani Kranthi and 33.45% in case of Arka Abhay). Whereas fruits harvested at 3 days after fruit set showed maximum visual spoilage in case of Arka Abhay (47.40%) (Table - 2). The pods harvested at 7th day after fruit set exhibited maximum days of shelf life. Where as pods harvested at 3rd day after fruit set recorded minimum days of shelf life in case of both varieties of bhendi. This might be due to higher respiration in tender fruits of bhendi. A non significant variation was noticed among the varieties and intraction between days of harvest after fruit set and varieties. These results are in conformity with Ratnapal et al. (1994).
